use single powerful led (30w-50w) as the light source,with the characters of high heat conductivity, low luminous decay, pure light color and no ghosting. •the led is closely connected to the crust. the heat from led will be removed from the heatdissipation wing and also by the air cross-ventilation. it can ensure its life-span effectively. •the lights were sealed by silicone rubber, it makes the heat sink, end cap and the glass combined perfectly with each other. the surfaces were passed the treatment like anodic oxidation and plastic spraying. it can meet the requirement of ip65. •use the high pure imported aluminum from germany as the reflector this kind of reflector has high reflecting efficiency, and it can make sure the luminous flux. the special design of our reflector can improve the light uniformity and utilization ratio. it can control the light inside of a useful area. the advantage of the led streetlights like power saving can be revealed adequately. •no delay start; no waiting. it can reach its normal light as soon as it is turned on. the switch can be used for hundreds of thousand times. •it is safe and removable, and it can be positioned at any angle. it is universal, and it can be used in a large scale. •environment friendly and no air pollution. we exert the design of using cold light source. it’s no heat radiation.there is no ill to our eyes and skin. the floodlights do not have lead, hydrargyrum and any other contamination. it is a real environment friendly and saving power product. •it’s an excellent partner of the solar panel system. it can exert many such as working with direct current and lower voltage. it is power saving and environment friendly. the connection of the solar panel and led light source provide a high reliability, a best feature and a reasonable prize to the clients. feature： model | led power | work voltage | power factor(pf) | luminous efficiency | initial luminous flux | gb290fl35wb | 35w | ac（85v～265v）/ frequency（50～60hz）dc（12v 24v） | ＞0.9 | 80lm/w | 2800lm | gb290fl40wb | 40w | ac（85v～265v）/ frequency（50～60hz）dc（12v 24v） | ＞0.9 | 80lm/w | 3200lm | gb290fl50wb | 50w | ac（85v～265v）/ frequency（50～60hz）dc（12v 24v） | ＞0.9 | 80lm/w | 4000lm |
