Which type of T5 bulbs would you recommend for a 75G planted freshwater setup? I'm thinking HO T-5s I'm looking for a specific brand and all that, getting to the point where I'm going to buy them so specifics would be fantastic! :)

Cheers

GE 6700Ks are the ultimate FW planted bulbs. Relative cheap and monstrous PAR.
Agreed...these are the best bulbs for the price. Once tested them and Geismann midday bulbs and growth was on par, but they are more then half the price. I think I paid $13 for them at Albrite. Best combination I found was a mix of 1:1 ratio of a daylight bulb like the GE's and a pinkish bulb like the Geismann Aquaflora or Aquamedic Planta. I am currently running the 2 GE's and 2 Aquamedic Planta bulbs. Best of both worlds. Growth and color. Using all daylight bulbs is great, but I can't stand the color look. Some use daylight bulbs with 10000k as well. Seems to work well too.

Its the only place I know of, but I am sure if you call commercial lighting places you will find them elsewhere.

As I am concerned Albrite does not have a retail outlet. They are wholesale distributor

Thanks guys that's some super advice there, I think I'm going to go for those 6700K albrite in combination with an aquaflora bulb, just hoping that light will be sufficient to grow high light demand plants!

Hmm that's very interesting thanks and a great price, if you think thats equal to around 150W then surely i'm only getting 2WPG for my 75G tank so perhaps I should go for a 4x54W T5HO?

Don't make the mistake of interpreting more light equal better. If you do 216w T5 HO with proper reflectors on your 75 gallon and you don't have your CO2 and ferts routine down, you're going to in algae hell. Spend some time perusing various planted tank forums and you'll see what I mean. I would point you to an old journal of mine on BCA, but since the crash, it's all lost. I went through that in my 125 gallon.

I'm not saying it can't be done, but the results may not be what you expect. Algae, outbreaks, heavy prunings every week, etc.

important to remember T5HO 54 watt is really 81 watts counted as 1.5 watts per watt.

haha.... listen to 2wheelsx2......

I too tried to play with high light not knowing what i'm getting into. Ei dosed the tank, ran a slight over dose of excell and dumped 50w of cfl lighting into a 10 gal and increased the photo period to 8 hours....... in 1 weeks time I had some green filiment algae.... followed by BGA.. upped the ferts and got green water.. hahaha..... learned my lesson..... cut the lights in half and the tank is back in control :)

Anyhow.. back onto topic. I'm not sure if your asking for specific bulbs now or if you are still shopping for a fixture. If you don't have your fixture yet, I would highly recomend looking at something with a nice reflector on it... it makes a HUGE difference!!.

As for the GE bulbs, i'm curious if anybody else sells them too...

Why not start with just a double HO T5 as there lots of plants you can have and they will thrive in your tank. Get a decent substrate, research your plants you want - low to medium light demanding - and go from there; this will also save you money on the light, electricity, replacement bulbs over the years (should be replaced yearly even if they look fine).
