With the dark days of winter rapidly approaching, I too have been experimenting with a home made light consisting of a 12v 20W MR16 halogen bulb, some aluminium tube and other bits and pieces from my shed. It isn't bad considering total outlay so far is under a fiver and it looks quite presentable too, which is a bonus.
The light output is good and it is certainly far better than the standard "position lights" fitted to my Pro Connect. However, whilst the MK1 setup described above is adequate for my lighting needs, I want more light! But being mean and tight fisted, I don't want to pay a fortune for the pleasure.
I am looking to use a couple of the MR16 Cree 5W LED lights as advertised on Ebay. They claim the same output with the much reduced consumption. The problem is, the specification states 12v AC input. Obviously I will be powering them with 12v DC from a battery. Does anyone know if this is a problem? I would have thought that as long as the polarity is correct they should light up. Or... just had a thought:- Do they have some form of rectification built in to take account of the AC from the transformers that usually power MR16s in domestic applications?
Any experience of using these bulbs would be welcome.
Kind Regards
Tom
