Default Very high-intensity flourescent lights

Well danny all i can say now is Holy moly! 54 watts!!!
I missed that one totaly as I searched with T5 lamp only and did not get
anything like that. A search with T5 54watt now shows me what everyone
is talking about. May I add OUCH! also, one replacment lamp costs as
much as I pay for a two lamp 40 watt fixture.

Okay I'm not as bright but I stick with dirt cheap for now.

By he way for those who have space for it Harbor frieght and tools has
their 10' X 12' greenhouse on sale for $599.99 or about the same price
i've seen on some of these fixtures.

Apparently these are high output T5 fixtures. The bulbs that came
with my fixture say they are 54W / 4200 lumens each, 216 watts for the
four tube fixture. That lumen output doesn't sound all that great for
the amount of power but it's ok I guess. They claim to be some sort
of grow bulb so the lumens/watt may not be the highest possible? I
just did a quick search and found another 54W grow bulb that claimed


to be 5000 initial / 4700 mean lumens. The eight tube fixtures are
432 Watts, so their output should be comparable to my 400W metal
halide fixtures but spread more evenly.. -danny

I'm not sure if your are getting all good information from the Guy at
the hydoponics shop. I've looked up the T-5 lamps specifications and
I only see about a 10% gain in light over a standard 40 watt. However
being small as they are you may be able to cram a lot of lamps close
together and get a higher amount of light.You could also do that with
T- 8 lamps which are a lot less costly. Here's the specs as I found
them between T-5's & T-12's;

T-5 lamp Width 5/8 in. Length 48 in. 28 Watts Rated Life
36000 Hours
F28W/T5/830 Color Temperature 3000K Lumens 2900 Initial/2726 Mean
F28W/T5/865/ECO Color Temperature 6500K Lumens 2700 Initial/2480 Mean
