So I've built some lights I used a mi-light Ls2 controller and some 24v led strip cut to 1m mounted on a 1/8" X1" x4' aluminum strip, the strips are ww cw rgb and can go any color including both cool white and warm white 4 strips and controllers use about 38 watts and when off the draw is .7 watts per controller, the aluminum strip keep the leds cool to the touch. And the controllers have a wall switch and remote and can also work with a phone with a wifi controller, each light can be built for around 15-30$ depending on the quality of led strip used I paid 16$ for 5 meters of one and 83$ for 5 meters Of a better quality led the difference is negligible time will tell.

    Connected directly to the battery means the voltage will go above 24V during charging especially, which would potentially damage the led strips, the minor losses of the supplied switching transformer would be worth using them, in my opinion.

    So the controller is rated at 32v so with a 72cell I hit 47 v and no problems yet, I will be switching to 4 60 cell panels so the voltage won't go over 32 ever and there is no supplied transformer with my setup it's all bought separate, the led is fine at 32 v even 36 v it's about constant current constant voltage I'm more worried about under 24 volts, also these are on a LiFePO4 pack so steady voltage between 26-27v
