Small form factor lighting, like candelabras

The XLamp XM-L High-Voltage led linear high bay light the trade-off between size and efficacy, allowing us to take advantage of the efficacy of high-voltage drivers,” said Ken Chakravarti, chief technology officer, Ledzworld. “This translates to more efficient, better and more cost-effective small LED lamps and luminaires such as the B10 replacement lamp for our customers.”

Small-form-factor lighting, like candelabras, historically presented a host of challenges for LED technology. Prior LEDs were unable to deliver the required system-level performance in the form factor consumers’ demand.

“Maximizing the LED voltage, as Cree has done in the new high-voltage XM-L and XT-E LEDs, is a very effective way to minimize current through the LED driver output rectifier,” said Peter Vaughan, director of led high bay light applications engineering, Power Integrations, Inc. “This can reduce losses and heat dissipation in the driver and increase the overall system luminous efficacy by several percentage points.”
