Basically it's just a duel motion light.. I usally do have just 100 watt in them.. but on one side I wanted a more powerful one to light up the parking area on one side.. so I'd have to ad more fixtures to use these.
Got it off Amazon. . Wanted a high light output.. to light up front of my shop.. think it was about 20.00.. had a control board and fan inside.. I think the control board burnt out..
I bought a 300 watt equivalent. . Think it only used 30 or 40 watts of power. Worked great for a month then quit.. I got refunded.
It had built in fan in the bulb.. I haven't tryed the smaller ones.. do they have a fan too?
