    Petsmart is selling t5 HO fixtures in two lengths (4 and 3 feet) but they only hold two lamps. I don't know how great they are. I think it's called GLO and might be made by Hagen or something. I dunno anything else about it.

    what i have the thermostat set to has more bearing on my electricity bill than what lights im using........short of using a bunch of 1000 watt metal halide type lights you shouldnt notice a difference in your electric bill. i have about 20 T8 fixtures for my plants and critter tanks and it doesnt affect my bill very much. for growing everything but Heli's and tall neps i dont see the need for more......im planning on getting a 400watt light one of these days to help out with the vining neps but other than that have seen no reason to switch from my T8's

    Rattler, you're right, I was under the impression electricity was more expensive. I guess I never did the math on my electric bill.

    A 100W appliance run for 12 hours a day costs around 10 cents a day.

    So, every 100W you add to your lighting setup is roughly another $37 per year. So it adds up, but slower than I realized.

    If that $135 fixture is over 200W, after a year it costs the same as the one I listed. It still seems worthwhile.

    true but you also have to look at cost of the bulbs.........costs me roughly $50 to replace all my bulbs every year.......im also growing plant and have tanks on roughly 24-30 linear feet of shelf space(most of the shelves are 18 inches deep) cheap HO T5's appear to be around $15 each on the cheap end.............when you figure my cheaper replacement costs i think it either is a wash or im slightly ahead in the cost factor....unless the HO T5's last significantly longer than the T8's.........not saying they arent good lights, just saying im doing it cheap and am having no real problems that i can see other than with the plants would benefit from something much stronger than the T8's at which point a large metal halide bulb makes the most sense cost wise to me..........

    Good point. I don't remember how long they recommend you use a T5. It's in the area of 18-24 months.

    IIRC the HO T5's come from the aquarium hobby where ppl are trying to push ALOT of light through 12 inches or so of water which is prolly impossible to do with T8's......they are also trying to get away from the heat produced by metal halide type lights.......they are producing a hell of alot of light and i would think they might be extreamly useful for growing Heli's on a rack system where you have a hard time getting a MH bulb far enough away so it doesnt burn them........however for growing most Drosera, pings, small neps ect.........i cant see where the price increase is worth it over the T8's....

    Could any of those work for lighting?

    I forgot where I read the information at, but it was from a legit source. Anywho, they said the bulbs (T5 HO's) put out about 95%+ up until they burn out. Basically, the advice that you should replace your bulbs every such and such amount of months is an attempt to get you to shell out more cash for bulbs. Sure, for some people growing certain types of plants (read illegal) this may be worth it, but they are fine for all CPs (for the life of the bulb). I personally love my T5 HO's but I also like the low heat factor from the T8's. Contrary to popular opinion, T5's are monster heat generators, and can be troublesome. This could be a deal breaker in choosing which type of fluorescent to buy, especially when the heat is being radiated into a glass tank. There are some T5 manufacturers that wisely place the ballast above the reflector hood and lamps, thereby creating an airspace between the two. I forget what the name of the manufacturer is, but i'll dig up the light and check it if anyone is interested. The reflector is somewhat convex, allowing for coverage of a wider area, albeit with reduced output. It should be noted however, that this does not completely eliminate the high heat issue.
