[QUOTE="Fred W, post: 1365371, member: 3828"] On that line... The ones that I have are rated at 40W each. My assumption is that this is in high beam mode with all 4 (both high and low beam) LEDs lit and the fan running. I do not know how much power the fan uses, and assume that it runs all the time, but if we discounted it from the equation, when the lights are on low beam and only the 2 low beam LEDs are running on each lamp, the power would be half of 40. So with the fan each lamp should be pulling maybe 25 watts or less, which is [I]at least [/I]half the power consumed by the halogen (50W low, 55W high) bulbs during running in low beam only, which is the daytime standard. Of course then I go and screw the power consumption pooch by running my LR4 Aux lights all the time, albeit PWM'ed to minimum intensity (and power use) on low beam. [/QUOTE]
