Just want to be able to put anything I want in it. They also have some that are 24, 26 deep.
if you get a 24 deep you could wing it with sps at mid way to the top with 24 leds, or places anywhere for 36 leds. personally i would do the 36 LEDS if you ever decide to upgrade in the next 5-6 years you will have a bigger fixture already ready to go
