LED Bulb Measurements, You Know, for Kids

Picture of LED Bulb Measurements, You Know, for Kids
As LED bulbs come down in price and up in performance, the viability of LEDs as a replacement for incandescent, halogen, and fluorescent lighting approaches a tipping point. I've been into LEDs for a while and have made many of my own bulb replacements and specialized LED fixtures. However, it is still nice to be able to drive my Escalade 7 blocks down to the local big box home improvement store and fork over some cash for a commercially made LED bulb while sipping my half caf mocha latte and chatting loudly and profanely with my buddies about the epic powder experienced during my recent ski weekend on a bluetooth headset, brah.

Toward that end, I recently rounded up a number of the LED bulbs I've bought over the past years and measured their power usage and light output using a kill-a-watt,  integrating sphere and light meter. The following details those measurements and presents a look into the economics and efficiency of today's LED bulbs. As this is a rapidly changing field I hope to keep these measurements somewhat current as new products are introduced. Due to the wide range of bulb types out there, I am concentrating on the most common style, standard A-series type screw in bulbs.
