One word of caution.

Do NOT allow these to be angled down into the home(s) where the point-source is visible to the occupants - these high-intensity LEDs are considered 'laser' lights - or at least have the same warnings that are given to laser LEDs.

I have three 5-watt LED lights that have been mounted on the wall of my home - pointed downward into my living room - basically shining right into my face. I could actually see the die when lit. They are pretty durn bright!

Well... after about nine months, both me and my wife acquired uncontrollable 'twitching' of the eyes. Very annoying, and I couldn't figure out why, until it dawned on me that it might be related to the LEDs shining in our eyes every night.

I left them off for a week - the twitching subsided. I re-positioned the LEDs to shine at a different angle, and everything seems to be much better now.

So - take care. I don't think that you want to harm anyones' vision with these enormous light-sources.

Regards,
