QTC in older Peaks

[jorgen]

I tried a QTC in a Glacier Bay with a Luxeon led. At low & high levels it works well but in the middle range the led flickers like a strobe. Any idea why?
I also tried the QTC in P4 Ranier and there was no problem.

My guess is that it may have something to do with the fact that the Glacier Bay is regulated (I believe), but the Rainier is direct drive ....

(and doesn't the Rainier use a P7, BTW?)

EDIT - just found something very interesting and perhaps relevant about the Glacier Bay on a web search ....

Take a look, about five paragraphs down

Regulation makes sense to me. I just never experienced this.
Current Rainier uses a P7 but the old ones used a P4. It isn't very bright but has a good span of lows w/QTC.
