If it's really 1700 lumens, then it's really more than 100we, no?
I've also discovered that, if using any dimming capability, that the circuitry really matters. I had some LEDWaves bulbs that didn't do well at dimming, swapped for near-equivalent Toshiba PowerCore bulbs, and wow, what a difference. I can tell that the Toshiba bulbs are really smoothing out their power draw (the dimming lags the input from the wall dimmer by about 1/5th of a second) and they sometimes overreach by going a little dim or bright sometimes as they guess where I'm trying to dim to, but I'll take it over the typical dimming failure mode (flashing).
It's exciting that LED bulbs have really come a long way in the past year. And I'm glad congress didn't pass the attempted repeal of the efficiency standards.
I have a 150we par38 above the kitchen sink - wasn't cheap - but my wife liked it a whole heck of a lot better than the 120we CFL that was there. You can't underestimate the value of no warm up time.
