This doesn't necessarily mean much. Standard fluorescents are also much
more efficient than regular filament bulbs. Watts per gal calculations
are based on fluorescent or MH output, not filament bulb output.


Energy consumption is 9W + 2W (with adaptor) = 11 watts.  Anyway,

Well it can't be equal to both a 40W filament bulb and a 30W standard
fluorescent, because the fluorescent is much brighter. The
manufacturer's claim is the more modest one, and I don't suppose they'll
be understating its performance. They may be great bulbs, but I can't
believe that they're more than 3 times more efficient than standard
fluorescents.

You can get the Philips bulbs at Grainger. The 13W 5000K bulbs go for about $7
and the
9W 7100K blue sells for about $9. The Ballasts can also be bought there. The
thing I 
had a problem finding was the sockets. I did find them at another lighting store
for
about $2.50 each. Oh, The ballasts were about $3.

I bought my seperate ~5000k bulbs, sockets and ballasts for 13w Osram
for about $12.50 a set from a builders lighting supply.

They are bright but the ballasts run pretty hot and wiring multple bulbs
close together requires some planning. I think that they are a good solution
for small <10gal tanks.

Well, if you consider the discount retail parts prices, it's not all that 
expensive.  A normal 11 Watt 4100K U-bulb with a ballast will cost you some 
$15, another $2-3 for the cord and switch, $1 for the mounting hardware,
$3-4 for the reflector -- and you are easily over $20 for a DIY light.

I had a chance to talk to one of Biotope people at a BAKA meeting and it 
seems these people are operating somewhere between serious experimental 
agro-science and a cottage cultivator black magic.  Biotope has an ad in 
FAMA and they seem to invite calls and questions.  Call them and ask them
for their experimental evidence that what they have is worth buying.

I'm using the Osrams PL/s for my little SW tank - I use 2 13 watt 'white'
bulbs (5000K, I believe), and 1 9 watt, blue (7100K) bulb.  Seems to
work ok.  Mine is pretty much a DIY thing (the hood only came with one
bulb originally).  My dealer carried the parts and supplies - ballasts,
sockets, etc.  He went out of business, so it's great to hear that
Grainger also carries these.  This is MUCH cheaper than coral lifes set
ups!!  Though even coral life can be purchased cheaper thru mail order -
I know Debron Aquatics has had good prices.

Again, my use is for SW (some soft inverts - mushrooms, polyps,
anemones, etc.), so I don't know how these will do for plants. (my hair
algae grew pretty well :-) :-)!)  Can you mix the 5000K and 7100K
instead of a 6000K, for plants?

Yes, yes!  But then I was most interested in the 9W 7100K bulb - do you
have that one?  Actually, even for the 5000K bulbs I would learn to
venture into the world of the Krib! (:-)  I'm a SW person - been looking
for a while, and finally found a picture of a 'krib', and that's about
all I know!)

Kristi Bittner

PS  oh, by the way - for those who might get fooled like me - the 9 and
13 watt bulbs look the same, except for length.  HOWEVER, neither the
ballast OR THE SOCKET are interchangeable - they don't really fit!

I believe there are actinic PL bulbs available now.
I guess adding a couple would raise the average color
temp of your lighting.
I'm going to try a couple of regular actinic tubes in
my FW tank (2 of 8) and see what happens.
Let you know!

First of all, that's not nearly enough light for an anenome.  The minimum
recomended amount of light to keep anenomes is 4W/g that setup only gives you
2.7W/g.  (I really don't want to get into the whole Watt measurments are
useless discussion, cuz the fact remains it won't be enough)

Let me tell you what I have done.  I have made a DIY hood for my 10g reef and
saved a bundle doing it myself.

I used two Custom SeaLife 28W 6700K Linear Quads and one 9W Blue bulb.  That
gives me about 6.5W/g of light, plenty to keep anenomes.

I went to Home Depot and picked up two light fixtures that hold linear quad
lights, normally used for outside your house.  I hacked them appart to remove
the electronic ballasts and the fixtures.  (I think there about $15 each)

I called Champion Lighting and ordered a ballast w/socket to run the 9W blue.
(about $20)  (Home depot sells 13W light fixtures so if you can get the 13W
blue light you can go that rout for a little cheaper)

I built the sockets into my hood and ran wires to a box containing my
ballasts.

All done.

My setup is a little large then your availble space, but the bulbs are spaced
out a bit, it may fit in your hood if you are clever.

Cost was about $80 including the bulbs.  The Custom SeaLife with only a
single 28W and 9W bulb costs about $75.  So I got a custome hood/light setup
with more light for only $5 more.


Let me know if you would like a more specific description.

Good luck

Cheap Cooling Fans

by Cbbgthdr/aol.com
Date: Fri, 16 Oct 1998

I just bought a 2 Lamp 55w (110w altogether) Compact Fluorescent Retrofit Kit
for a 29 gallon planted acrylic tank. I glued it into my hood with super glue
and voila. An hour later I noticed that the sheet of acrilyc that one screws
onto the hood to keep water out had bowed considerably. I checked the water
temperature and it was 83 degrees F!!! Luckily the fish didn't seem to mind
too much and there wasn't any damage to the actual aquarium. I unplugged the
lights as soon as I realized what was happening.

I could just get a sheet of glass to replace the sheet of acrylic, but I'd
still have 83 degree water. Chillers are three hundred buck and up, way too
expensive for this college kid. Pet Warehouse sells a cooling fan kit for 50
bucks. That's 50 bucks for the fan (nothin' fancy either), two pieces of
plastic ("finger guards"), and a foam filter (a sponge). I'm not a poor guy or
anything, but that's like throwing your money at the wind. I mean how much
could the cheapo wiring in the fan possibly cost, and the finger guards cost
ten bucks a piece... for plastic. You can by a real (big) fan to cool a whole
room for under ten bucks.

Anyways, does anyone know where I can get a tiny 4"x4" fan and two finger
guards cheaply (around twenty five dollars). Maybe at the Home Depot or a
electronics store or some other pet mail order houses? Please e-mail me with
your suggestions and with *any* other solutions to my dilemma. Thanks.

Just a warning.  We recently bought these lights for a small reef tank we

were still in the box.  I got a call from the LFS asking ust to return the
light.  They have had several returned to them with the endcaps actually

the manufacturer.  They were very relieved to hear that I hadn't installed

Karen,

I haven't heard about the melting problem, but I've tried twice to order a
24" SHOlight from That Pet Place and both times it arrived broken in exactly
the same place -- where the heavy reflector/bulb/ballast assembly attaches
to the plastic cover (at four very flimsy attachment points).  Perfecto
packs them very poorly.  They basically just throw the thing in a box, with
no padding whatsoever to support the delicate parts.   So no matter how well
the mail order house packs it, a hard enough knock will break something (in
both cases the box from TPP arrived in excellent condition, with the
contents broken).  I've tried ordering another one from Pet Warehouse to see
if it fares any better, but I'm not optimistic.  The thing I like about the
SHOlights is they look narrow enough to sit on my glass canopy and still
allow me to open the access door fully.

I too have ordered the Leviton lampholders. I like the lampholders from E. Gaynor Corp. a lot better, but they cost a little more.  

Motorola's disclaimer was probably written by their legal department rather than by the engineers.  UL listings are for very specific combinations of lamps and ballasts, and any other combination would not be approved.  But some manufacturers (not Motorola) do list their T8 electronic ballasts for use with F40/30BX lamps (both require about 270ma).  F39BX lamps operate at 430ma, just like a F30T12 or a F40T12. I would venture to guess that they were originally designed to operate using existing F40T12 ball
asts many years ago.  So from the ballast's perspective, the lamp easily falls within its operating range.  The problem will be whether or not the ballast provides enuf starting voltage to ignite the lamp.  And the combination may not be UL approved, not because it is unsafe but because the manufacturer has not paid the $$$$ to have that lamp/ballast combination tested and listed.

Fan noise in CustomSeaLife ABS hoods

by boingy/ugcs.caltech.edu (Heide Li)
Date: Mon, 26 Jul 1999

(a bit behind on my APD reading.)

Hi Michael,

I've got a 24" CustomSeaLife ABS hood with 2 55-watt bulbs,
though lately I've only been running one of the bulbs on
my 29 gallon tank.  When I first got it the fan noise drove
me nuts, too!  Since the bulbs don't run very hot (even
without the fan), I decided to just replace the fan with
a quiet 12VDC computer case fan.  I used a small DC power
transformer that can output at a range of voltages, so I
can run the fan slower (and quieter) if I want to.  Usually
it's set at 4V, but on hot days I sometimes turn it up to
the full 12V.  It's been working great for 7 months now.

Oh, I also stuck small (1mm thick) strips of rubber at the
corners of the fan before mounting it to the case, to help
avoid vibration noise.

On the con side, I'm sure this method voids any warranty on the
hood/bulbs.  :)

Hope this helps,

CustomSeaLife carries the Panasonic bulbs.  Hamilton Technology carries
German & Panasonic bulbs (of course that you may specify).  The 2 types of
bulbs, their end-pins and the end-caps on the fixtures are all different and
*incompatible*.  So once you have decided on one type, you will have to
stick with it.

According to the advertisement by Hamilton, some of their German bulbs are
30% brighter and the blue ones are genuine actinic blue, instead of the
Panasonic's 'blue'.  I don't really know whatever that means or whether to
believe them or not.  But I am merely reproducing what their ads say.  I
have no info on the ABS fixtures or cooling-fan used either.

There are other newer compact fluorescents released onto the market as well.
One manufacturer being Philips, another being Osram, then some brands from
Asia too.  In Asia, they called the CF bulbs PL lighting.  Some of these PL
bulbs have bi-color on one tube.  That is, one side white and one side blue
on the same bent tube.  Pretty unique.

Merry X'mas to everyone!

PC vs standard flourescents.

PC lamps are not more efficient than normal fluorescents. The long tube ones 
are about the same as linear lamps, and the short tube ones are not very 
efficient.  The most efficient fluorescent lamps that I am aware of are 4 or 
5 foot long T8 lamps with "800" series phosphors.  If you have a 4 foot long 
tank you should seriously consider using 5000K F32T8 lamps and an electronic 
ballast intended for general lighting.  I would try using a 4 lamp 
instant-start ballast that is capable of driving 3 lamps to a high ballast 
factor (like 1.1).  Then use 3 Philips "Ultralume Advantage 850" (I think 
that's the right name) lamps.  They give you 100 lumens per watt.  Equivalent 
PC lamps with the same phosphors would give you about 86 lumens/watt.

You also might build a hood that uses four 39W PC lamps (22" long with 2G11 
base) and operate it with a 4 lamp F32T8 electronic ballast.  The lamps would 
cost more that 4' linear lamps, but you could get a lot of light in the 
equivalent space as two F40T12 lamps.

Dan, PowerCompacts are what is called single-end fluorescents
(pin-wise)and are almost standardized.  I say almost because apparently
you have to change the sockets if you want to swap 55W Japanese tubes
for 55W German tubes.  Anyway, Hamilton does not make their own bulbs,
they're made in Germany and Japan.
Extended bulb life: Customsealife (who uses the same bulbs) says it's at
least 12 months and Hamilton recommends replacing them every 14-16
months.
That's not really all that long and Customsealife even tells you to
replace them after 12 months, regardless of lighting cycle and operating
temperature.
Increased efficiency: go to
http://customsealife.com/cost_calc/cost_calc.html and use their cost
calculator to see for yourself how much more/less your system would
cost.
I've been looking around for cheaper prices myself and the best I've
found so far are at Jeff's Exotic Fish -
http://www.exoticfish.com/default.htm
Pet Warehouse's prices (www.petwhse.com) are within a dollar for the
smaller models.
Hope this helps,

Compact Flourescent retrofit kits

by "Bob/Georgia" <luna/mail2.nai.net>
Date: Thu, 26 Aug 1999

Just a short note about the AH Supply CF kits. My kits (2 X 55 watt) were
shipped on Monday via priority mail and they were delivered on Wednesday. It
took 1 1/2 hours to convert my Perfecto Double Bright 4' strip light. The
results have me very pleased. I called Kim twice for advice and he was more
than willing to answer the questions I had ! If you have been contemplating
these kits I recommend them for anyone a little handy with hand tools. It
only takes some basic tools, drill, screwdriver, wire stripper and a
screwdriver to do the install. The strip is noticeably brighter than the
Perfecto SHO strip light that it sits next to and I now have 220 watts of
5400K CF on my 55 gallon tank! You can find a link to AH Supply on my links
page at: http://w3.nai.net/~luna/Fishpics/Fishlinks.html If you have an
interest.

Ballast info.

by Steve Bansee <Steve.Bansee/PWGSC.GC.CA>
Date: Fri, 23 Jul 1999

Hi all,

Don't know if this will help anyone, but... I'll post what I have found.

I am thinking of making a new hood and increasing the amount of light on my
25gal tank (just got the high pressure CO2 setup from Dave G., way cool).  I
was planning to use 55w Power compacts, found a source for everything
locally (Winnipeg, Manitoba, Canada), but the ballasts were pretty expensive
$70 CDN or so.  Soooo I called Fulham Ballast (www.fulham.com) and asked
about a ballast that will run two 55w PC, cost $12.00 US.  I think the same
ballast are used by AllGlass and CustomSealife.

SHO-light recall

by PGagne2000/aol.com
Date: Wed, 27 Oct 1999

My LFS owner just told me about a recall affecting my Perfecto SHO-light, and 
gave me a copy of the letter.  It says that the layout of the wiring and/or 
possible excessive heating in some lights can create a shock or fire hazard, 
and to discontinue use immediately.  The affected lights are ones which were 
built in July '99 or before, and all 36" lights with two bulbs.  Perfecto 
will repair the lights for free.
I'm sure the repair is pretty straight-forward on all but the 36" lights.  
The letter says that the (double 55-watt bulb) 36" units will be replaced 
"with improved, single-bulb 36" configurations."  Since I bought the light 
for the combination of high output in small package and price, this didn't 
sound good.
I called Perfecto, and sure enough, the single bulb is the same one I now 
have two of.  When I explained to the woman on the phone why this was 
unacceptable to me, she said she would see if I could be shipped two of the 
new units in place of my old one.  When I wasn't thrilled with this either, 
she said Perfecto would send me a box to ship the light back in and issue me 
a check for my purchase price.
Just thought I'd let you know, since Perfecto can't reach all their customers.
Perfecto can be reached at 1-800-241-7485 from 9:00 to 5:00 EST on weekdays.

Get the 6700k bulbs only. I tried both set ups and found the 6700k's did a
much better job with many plants. The blue reef bulbs don't do much and
don't grow the plants that well as nothing but the 6700k's(I had a 55watt
7100k and a 6700k then switched to 2x6700k). Add a 5400k bulb if you can
find them also but 6700k's by themselves certainly do a super job. I also
use a Hamilton fixture and am very happy with both and there's not much
difference except Hamilton is cheaper most times. I believe
www.reefpacific.com has the best prices for retrofits from many mail order
places. 215$ 36" for 2 x 96w retro kit. Worldwidepetsupply.com has good
prices on full hoods too. They'll  also give a choice of bulb color and how
many bulbs in a specified length of hood (4(599.99) or 6 (769.99)bulbs x for
a 72" long hood). I got the 6x96watt
hood with 6700k's and it's very nice and very bright.


If your handy or know someone who is... you can build a very nice unit from
AH supply for alot less than CSL/Hamilton sells them. All you need is a nice
box to hold the lights in and put it all together.
They sell all the bulbs too.

Tom Barr
