one doesn't say how many watts the t5 are in it surely they wouldn't be that much it says the MH
is only 150w so that would make the t5 globes 245w each if thats what your saying. Did you mistake the length for the watts because the length is 640mm long which is just over 25 inches.
1 x 150W 20 000K UV Block Globe + 2 x NEW T5 High Output Floro Globes.
that's what it has i don't know if having an uv
light is better or not but i would change it if need be
agreed though the T5 AQUARIUM OVERHEAD LIGHTING 8x42W 600 Long does indeed have alot of watts so thats out
my tank in inches is ( 29.5 )
currently i have a 2ft ( 24 inches ) light on my tank
they have got there measurements wrong they are saying it is 645cm
( that's like 254inches ) long which would make it one big light and it certainly don't look that big in the photo it's suppose to be 645mm ( just over 25 inches )
