You would probably be best looking online at like Hellolights.com and ReefGeek.com for T-5 retros. When reefers are talking about T-5's, unless stated otherwise, they are talking about T-5 HO
. The ones that are sold at hardware stores are pretty much always NO, unless they sell lights for horticulture, and are not really ideal for frag tanks, unless you have a lot of them and that wouldn't be really efficient.
means High Output
NO means Normal Output
What kind of coral(s) do you plan on fragging?
I am about to set 2x ten gallons (connect, one above the other) as frag tanks and I'm still trying to decide what I want to use (70,150,175 MH
or 2x 24 watt T-5 HO
, or overdriven T-5's)
Quality reflectors are extremely important and one thing usually overlooked by people is the importance of water clarity for light penetration.
Many, many options. HTH
