Do you have a recommended dimmer to minimize flicker while dimming?
I installed new recessed lighting and looking for quality LED bulbs with matching dimmers. I'm personally sensitive to color and flicker gives me headaches. I'm looking at the 4011.30.6P. It shows a flicker of 6%. Is this low flicker amplitude maintained while dimming. It appears Lutron and Leviton dimmer are mentioned as compatible. Any particular dimmer recommendation to minimize flicker while dimming?
We ran a series of dimming tests using a Lutron CTCL-150 and confirmed that the flicker performance is indeed best at or near 100% brightness, where we observed ~7% flicker and 0.02 flicker index.
As the brightness setting is decreased, flicker percentage increases to ~11% with 0.03 flicker index. Given that traditional incandescent lamps exhibit flicker rates of 15% and higher, this performance is in line with, or exceeds that of traditional incandescent lamps and should not present any issues for most residential installations and applications.
Attached are the test results as well as a plotted chart of the results.
Do you think the performance will be similar over the full line of Lutron LED+ dimmers or do you think this will vary substantially from one dimmer model to the next?
We've just repeated the test with the Lutron TGCL-153PH series dimmer and saw the same results (7-11% from high to low).
While we wouldn't be able to draw any conclusions from just these two tests, we now do possess two sets of data points for Lutron performance which may give us some further confidence regarding dimming performance across brightness settings.
