Makers of directional lamps now have a more affordable LED option that offers single-source beam control: the Philips Lumileds LUXEON 5258. This multi-die emitter enables the most cost effective design of PAR 16, PAR 20, MR16 and GU10 lamps using existing drivers at 24V and 96V.

“We are providing a high flux, high efficacy LED that improves the quality of light and avoids the unfortunate “showerhead effect” that users experience with distributed, multi-die solutions. The LUXEON 5258 can achieve lower system costs compared to solutions using multiple LEDs for 35W and 50W MR16 today,” said Ahmed Eweida, Product Manager. Lumileds initial offering of the LEDs in the 5258 plastic package is in warm white CCTs with a minimum CRI of 80. The 24V solutions provide 425 lumens at 110 lm/W, while the 96V solutions provide 400 lumens at 105 lm/W. However, both can be driven to deliver up to 650 lumens.  A 5mm diameter optical source enables precise beam control in directional applications.

The LUXEON 5258 is designed to provide the best efficacy and flux metrics with superior reliability and droop curve than all competing solutions on the market.
