rotating lights???

have to think to about power consumption the motor to rotate the lights is going to draw a lot more wattage than just the lights and it will take need swivel so the wires dont twist togeather and wear down the insulation resulting in a bright light and a big bang.

Not saying it cant be done but the cost might start going up rather fast.

not to worried about power consumption ive shut down three tanks with a fourth about to be shut down just to do this one lol

Don't those slow stepper motors use very little power? Maybe I'm thinking of something else.

well then you got lots of extra power. If you need help wiring it let me know I can walk you through it (gotta love being an electrician)

depends on the motor really, some are strong output some not so much.

Aren't there horizontal light movers available (also spawned by the hydroponics industry)? These would work better on a rectangular tank and you would actually save money by only using a single halide and having the device move the light back & forth over your system. That rotary thing looks scary and ill suited to even a cube. Good for a cylindrical tank maybe.

my tank is a cube its 48" x 48" only my height isnt as extreme as chin lee's mines 20" .im not set on it yet i have made the decision that im going to use a circle ring to mount 4 pendants its just someone mentioned that i should go rotating and i was like " really" "they do that??" lol so i was curious and now that ive seen someone with that im even more curious haha what have i got myself into now lol

im guessing the problem lies in that i have 16 sq/ft that needs to be lit up without using fixtures on legs or having lights covering up the whole top so if i can make a sleek giant "metal washer" i can bolt four pendants onto them just offset slightly from the middle......and thats where rotation got brought up lol

Well then your giant metal washer idea with four pendants sounds good. Not much need to rotate something like that I reckon. Would make things overly complex for no real benefit or reason.
