I ordered a few of these
http://dx.com/p/gu5-3-3-5w-6500k-420-lumen-60-led-white-light-bulb-12v-131888
from Dela Extreme. I hooked them to my homemade LM317 power supply (it has no current limitation). I connected an amp meter and measured over 1 amp.
I assumed these bulbs had their own current regulation but they are advertised at 3.5W
At 3.5W I should only be drawing less than 300 ma correct?
Am I correct to assume they don't have current regulation?
