◆ Adopting GENUINE NICHIA LED, lumens of natural white upto 700Lm, and of warm white up to 600 Lm. ◆ Its form-factor guarantees a 100% form-fit on the back-sideof the lamp(exact form fit with halogen lamps) ◆ Delivers a beam intensity which reaches that of a 50W halogenlamp. That it can replacement for 50W halogen lamp directly. ◆ Dimmable down to 15% with most of trailing edge dimmers,when in conjunction with recommended electronic transformers. ◆ 0-100% dimmable with PWM or 0-10V dimmer. ◆ It uses an active power factor correction structure to controlthe input current, so that the PFC can reach over 0.95 whenin conjunction with electronic transformer.
