> Hi, > > For me T5 means that for the same 4' length I get 54W instead of 36W - 50% more. Which means in a typical case the difference between 2wpg and 3wpg. Can't gain much in space cause I am reflector width limited and am not willing to pay for the special hoods - not yet. > > Aviel. Aviel, If you want cheap you can still get a lot of light with NO Fluorescents. I have six 40W bulbs (6700K) in my home made hood for my 75 gal (240W - 3.2 W/G) for about $150. The bulbs are 2 for $6.50 at Home Depot at last for years. see: http://users.ev1.net/~spituch/Steve's%20Page/Aquarium/hardware/lights/lights.html and http://users.ev1.net/~spituch/Steve's%20Page/Aquarium/Animals/animals.html Regards, Steve P. ------------------ To unsubscribe from this list, please send mail to majordomo@thekrib.com with "Unsubscribe aga-member" in the body of the message.
