HID modified THOR-X (Cyclops) 10 Mil. Cp. spotlight...

New to the forum. Thought I'd share... Having built a couple of sets of HID automotive headlamps, I had some leftover parts kicking around and an old 10 million CP spot/flood light. The 12v SLA battery was junk and I hadn't used the light in years. Time for an upgrade...! I picked up a new battery, LED volt meter and some spare HID parts around the basement. The original bulb was a 55/85w H4 automotive type bulb. I replaced it with a 35w 5000k tilting HID burner and a slim ballast that tucked nicely under the reflector dish. I carved a window in the top of the housing to put my LED volt meter to watch the charge and discharge states. One of the existing power switches now drives the ballast, and the other the tilting magnet to give me the spot/flood light output. The internet says HID bulbs are 3.5x brighter than halogen, so I've created what? A 35,000,000 candlepower monster? The original run time was just about an hour with the halogen. I timed the conversion at just about 2 hours runtime until the ballast shuts down at around 8.5v... Enjoy!

Welcome to CPF! but no, it's no where near 35 million.

thor 15 million real candle power is about 0.4 million,
thor 10 mill probably 0.2-0.3 million
HID is 3.5x more efficient at same watt, but you shrunk the power from 85 down to 35W, so you are marginally brighter than stock 85W incan, probably 0.35 million cp or so.

It looks brighter than the stock thors to me, though its hard to tell from pictures. Good first post.

Its a beautifull round beam, like it

nice spot !

Thanks! I did spend a little time adjusting the position of the burner with my Dremel to get the best output. The first photo is 112 feet away, the second is 88 feet away, according to the measuring tool on Google Earth...
