These old CREE bulbs were purchased probably 15 years ago when they first came out, with a subsidy provided by AEP to replace standard bulbs. They've been good - I've only lost two of them over that time, one to a severe cold snap that destroyed the supply inside (that one had been on for 10 hours a day 7 days a week for 15 years as a door lamp) and one that just had early mortality.

I hate to get rid of them, but modern capacitive dropper LED bulbs are quieter RF-wise, and produce less heat than these massive switching units. I'm sure someone can use them, however.

This is posted in oldtechnology because these bulbs, at least this style, is highly obsolete and is ancient for it's type of technology - even though it's still "modern" in some ways.

Not any more.

There's still a regulated driver in them, but AFIAK all devices these days drop the voltage down using that big electrolytic.

These old CREE bulbs actually have a real switching supply in them, thus the big heat sink at the bottom.
