Constant current drive, it is good for led tube's working. (2) ac85-265v, 110v, 120, 220, 230v, 277v. Completely meet your needs of voltage. (3) high power factor(pfc): > 0.95, high efficiency: >85%, heat lower, more life for led tube. (4) open circuit protection, overload protection, short circuit protection, long-life design. 2. Led source (led lamp bead) (1) the chip of led is of high quality and bigger size, 10*23 chip. (2) it is from epistar in taiwan. It can resist higher anti-static and distribute more brightness. (3) high brightness with 7-8lm per led. 3. Shell (1) aluminum back cover, good for heat dissipation (2) frosted pc cover, light transmittance up to 88%. Transparent (clear) cover, light transmittance up to 96% (3) products are without environmental pollution, no halogen, high temperature resistant, cold-resistant (4) pc cover is good for tenacity and quakeproof 4. Warranty and certificate (1) warranty: 2 years warranty. If the product have quality problem itself, we provide replacement. (2) cetificate: ce, rohs Package:carton Size:120*20*24mm
