Compared to previous CALiPER testing, the LED tube light lamps showed notable performance gains, with the efficacy of many products equivalent to or exceeding that of fluorescent tube lamps (with ballast). Likewise, some of the LED tube lamps had similar color quality and power quality to their fluorescent counterparts. But none of the LED light tube products matched the luminous intensity distribution of the lamps they were intended to replace, and only a handful provided comparable lumen output.wholesale compatible with electronic ballasts best quality 18w led t8 tub8 8 led tube japanese t 100v 277v ac ul dlc .18w 4ft led t8 tube with ebay 1200mm ul vde supplier ce rohs high cri 2ft 3ft 4ft 5ft t8 led tube light(tj t8 radar ebay) .Both LED lighting tube fixtures can replace a range of legacy high bay lighting systems¡ª250-watt to 1500-watt high-intensity discharge (HID) and four- to eight-lamp tcob mcob cob led tube light 1.5m T5 T8 high-intensity fluorescent lighting, which typically burn out after 50,000-60,000 hours.
