Berezny Your discovery about incandescent/halogen bulbs after the 72W mark no longer flickering is a fascinating tidbit.

I have a question mark about this one.. what happens with 130v bulbs on a 120v circuit? They still consume the same power in watts, but the lumen output is reduced by about 25% due to the voltage difference so a 100w 130v bulb puts out roughly the same amount of brightness as a 75w bulb and I guess a 60w 130v bulb would appear like a 40w 120v bulb. So does the 100w bulb flicker or not when the voltage is different? Looking into it further, maybe I was mistaken about the wattage staying the same.. I read that it also goes down to about 85w but this would need to be tested with an actual meter to measure how much power is consumed at the plug before and after.

    Great database thanks! Could you add the GE Relax/Reveal/Refresh series of high CRI LED bulbs?

    A bigger problem than flicker/CRI/etc is longevity sadly. These GE bulbs claim 13 year life on the box - lots of mine are failing at ~9months. GE has already sent me coupons for some replacements, but it is getting a bit silly.
