Lighting Research Center Investigates Dimming Behavior of LED Replacement Lamps

Designing LED replacement lamps that are compatible with residential dimmers is complex given the diversity in product performance, creating a challenge for manufacturers to design lamps compatibel with a wide range of dimmers. On behalf of ASSIST, the Lighting Research Center investigated dimming performance of a range of LED replacement lamps, CFLs and incandescent lamps and residential dimmers, focusing on min/max light output along the dimming range as well as in-rush and repetitive peak currents.

LRC reported:

“In general, it was found that a lamp’s performance with one dimmer does not predict its performance with another, and that the dimming profile of a single incandescent lamp can vary considerably from one dimmer to the next.”
