OK, I was staying on the simple side of things, thats all. Not a transformer in them though last one I pulled apart the base circuit was a tiny high frequency PWM IC, tiny resistor & zener to regulate the voltage. Very simple.

Watt Test was not a light test it was measured on bench test for power consumption. Lux test was on the kitchen bench with them installed in the ceiling moving the meter around the benches in the kitchen was an average and they do actually have a reasonable spread on the bench or I would have pulled them out right then.
Good heat-sink on the light and after a couple of hours running still only slightly warm to the touch no I did not measure the actual temp I should have. I have a temp probe for the multimeter I was doing the testing with. I simply forgot, they have been in now for about 12 months and they are dimmable although they are never dimmed at all, neither were any halogens when they were there either. As for the cost they were about $12.00 each so not OTT for the actual globes.
