The XF BR40 LED bulbs provide high quality lighting and superior lumens-per-dollar performance using the latest in LED technology. The lighting system uses 30 Lumileds LEDs in industry standard 3.0mm x 3.0mm SMD packages. These epoxy molding compound (EMC) QFN packages feature high luminous efficacy, exceptional reliability and excellent lumen maintenance. The XF series comes with two drive current options and is available in 25W and 30W models that produce 1800 and 2550 lumens respectively. These workhorse LEDs deliver high lumen density that is excellent for directional flood lighting applications. The BR40 LED bulbs come in standard 80+ CRI with a wide range of CCTs. Optional 90+ CRI allows colors to be rendered with high fidelity, which is well suited to visually demanding applications for preventing eyestrain, improving visual comfort, enhancing room ambiance or increasing workplace productivity.
The bulged reflector bulb features a superior integration of mechanical, thermal and optical elements. An impact resistant, high strength polycarbonate diffuser protects the light engine from dust ingress. It balances clarity and diffusion to provide high transmittance efficiency as well as uniformity of light diffusion. The bulb comes with an aluminum construction that provides mechanical stability and thermal dissipation. The powered coated aluminum housing serves as a high performance heat sink and is assembled with an ignition resistant polycarbonate housing to complete the sleek design. The vented aluminum housing facilitates both thermal conduction and convection. An adequately dimensioned, low resistance thermal path allows thermal energy to be transferred to the ambient environment in high efficiency.
The XF BR40 LED bulbs are operated by a constant current driver which combines power conversion, load regulation, and dimming control. The driving circuit provides high efficiency power conversion and excellent load regulation with high power factor (0.90) and low total harmonic distortion (THD) over 90-130, 180-240 or 100-240 VAC input range. The dimming circuit is compatible with most phase control Triac dimmers. This driver circuit provides 750mA current with minimal ripple in the output current provided to the LED load, which ensures flicker-free illumination.
