The tri-proof led light fixture adopts 220lm/w SMD2835 led chips as the lighting source can achieve high lumen out put. The PC diffuser (transmittance 86%) and the high lumen led chips make the led batten light higher luminous efficacy. The CCT of the led batten lights have 3000K/4000K/5000K/6000K option. The led batten lights with sensor dimmming function can change the color temperature by sensor. The housing material of the tri-proof led light fixture is Polycarbonate.
