Yes, those will run fine on 12V. Just make sure that the output from the transformer or supply that you will use to power them is DC and not AC.

You have raised an important point. My interest in LED lighting stems from building LED lights for mountain biking.

For these lights we try and use white LED's with the lowest possible colour temperature. The closer you can get to "Daylight" the better. The reason for this is that when using very high colour temperature LED's which have quite a blue light it makes it more difficult to pick out detail while riding at night, however, when using LED's that are closer to daylight, the illumination they give is much more natural and easier on the eye's.

I would imagine that they same applies to using LED's for a work light. The closer the LED's colour is to the daylight 5500 to 5800k range the better. Unfortunately these "Daylight" led's tend to be more expensive and not nearly as common as the bluer ones.

However, I don't think even LED's with a very high colour temperature would get as high up as the  8000k of that CCFL tube. I think 6000k to 6500k  is more typical for most white led's.

Compatible with the transformer. When it arrives?  :scratch:

Hi David

Those should work fine with the transformer.

Good find, just ordered a couple of those myself, I am sure I can find an old laptop power supply around 12V somewhere that should do the trick  :thumbup:
