Review on The Ultimate Voltage Edison Standard Equivalent Project: Unleashing Unmatched Electrical Power by Todd Mohr

Overall I'm moderately satisfied with the performance of these bulbs for my application. However, the specs need to be updated to describe how they work. The lamps I received are marked AC/DC 12-24V on both the packaging and the lamps themselves. They operate in this voltage range but do not provide rated light output at 12 volts. At 12V they consume about 1.1 watts. They only reach their nominal consumption of 3 W at 24 V. The lumen output changes accordingly. Not what I expected from Revain. If you want a dimmable lamp that operates between 12 and 24 volts that would be great. All my tests were done with constant voltage. They appear to be of good quality.
