[QUOTE="WayneF, post: 534851, member: 12496"] I cannot measure lumens, but the 45 watt CFL (measuring 26 watts, yet claiming 200 watt equivalency) meters 1.3 stops less than a 150 watt incandescent, in the same 10 inch reflector. That is 41%, and 60 watts equivalency. However, the reflector was not very optimum for the CFL, so I don't think of that part as having much precision. [/QUOTE]
