Bright LED lamp as a fluorescent tube replacement with high efficiency.This bright LED tube achieves the same brightness as the previous T8 fluorescent tubes.Advantages of the LED tube compared to the old fluorescent tubes are the low power consumption,very long burning time and high light output.LED tubes are also practically maintenance-free, which reduces the amortisation period and maintenance costs.Lifetime 50000 hrs - corresponds to about 20 years, during which you save a lot of electricity and do nothave to change lamps.LED tube 60cm ( 170 SMD LED) replaces TL 18W T8,Luminous flux: 1050 lmLight colour: 4000K white ( from 50 pcs. also available in 3000K or 6000K daylight)Colour rendering: Ra > 80Wide beam angle: 180 degPower consumption: 9 WattOperating voltage: 12V and 24V DC (10V - 28V) - not for mains voltage !The electrical connection is made at one end of the tube. The other end is bridged.Reverse polarity protected: +- can be reversedBase: T8, G13 - like standard fluorescent lampsMaterial: Aluminium and cover milky polycarbonateApprovals: TÜV, CE, EMC and RoHS, CEI EN 62776.Sale to trade or industry only.
