Before you read on you should know that these lights are 500W each, so 4 is equivalent to running a kettle.
The outside of the lights can reach 180 degrees C and the heat can be felt from several feet away.
I have around 12 stage lights I no longer need. I planned to convert these to regular ceiling lights, but never got around to it. Some are complete, some partially dismantled, but will go back together. I can't confirm they all work, but at least one does. I suppose you could use these as they are, but they're very powerful and get very hot. I also have some coloured filters and front grills.
If you're interested, let me know how many you want.
