Tyson:

OK, thanks.  As I said, I didn't have the guts to try to take one apart.  (Yet) Too bad they don't come apart like a CFL...remove guts and re-assemble.  Once again, very nice job on this project.  Hopefully, the depot will have another sale and I will obtain a few more.  I am sure that the prices will come down eventually.

I noticed on the box 'warm white' the glass envelope is probably cemented to it's base with a heat proof cement which usually is very hard. If you have a dremel and cutting disc then you may gain access that way or even a grinder perhaps. I've started to collect the  screw cap bases from scrap CFL's and mount my DIY  low voltage LED projects into these bases for my out door lanterns. Here in the UK for years our mains lighting has used (BC) bayonet cap lamps, however most lighting products are ES as you Guys use. Much better idea!
I'll post a pic of one of my 'home brew' lamps. Cheers Guys Crow

That carton shows 9.5W for 60W equivalent which is just under 0.09A assuming 110v supply. Intersting to know the current draw for equivalent brightness using your JT circuits! can you give a breakdown of it's dropper circuit.

Crow:

I would love to see some photos of your homebrew lights.  They sound interesting.  Are you able to get any of these new Cree bulbs in your area?

Here are some photos of my Cree, modified by removing the driver board.  It was not too bad.  I will be able to put it back together (empty) so I can screw it back into an Edison base to run in one of my JT light fixtures.  I am driving it here using my little handy box surplus flash board JT using an AA battery.  It lights up very well.

Thanks Tyson for showing me that this could be done.
Crow:  There is a photo of the little driver board...3 inductors, 2 caps and a smd transistor, resistors, etc.
