LED Lighting for 40 Gallon Breeder

[nyknicks4412]

Through some suggestions at my please! Looking to upgrade and am in the planning stages. I want to keep a mixed reef with a variety of corals. Prefer dimmable LED setups. Can do either DIY or in box system.

Price range is probably at most 1 AI Sol Blue...so that or anything cheaper is fine.

RapidLED DIY 36 dimmable kit cheaper than a premade fixture, better coverage since you choose the heatsink or aluminum channel, plus you can control it manually, with a reef keeper, or an apex.
