Philips MR16 500 lm LED bulb

Doing some new lighting with MR16 bulbs. It's a friction fit connector and, of course, one of the bulbs fell out and hit the floor and broke. In retrospect a friction fitting connector seems like a bad idea... at least it gave me an reason to do a tear down. Video at the link.

Nice review as always. There is a tear down of the original 415 lumen version here: http://www.candlepowerforums.com/vb...-watt-AmbientLED-MR-16&highlight=philips+mr16

The driver board in your video at 3:50 can be compared to the one in the link above. It seems that the board components are mostly the same, but there are a few changes. (And you soldered the '100' inductor backwards, but of course that makes no difference. ) OTOH, at 4:10 the LED board has a lot more parts compared to the earlier version.

I have several of the intermediate 435 lumen version and a couple of the 500 lumen version. I don't see the on/off flickering at the low end of the dimming range that you showed. So it is obviously dependant on which dimmer is used.

Did spreading the pins slightly allow the bulb to stay in its socket? In my case the bulb housings are pretty firmly held in place. So they do not depend on the friction in the socket.

Yes, thanks for the suggestion. The replacement bulb is much more secure. Thanks for the excellent teardown link on the previous version.
