NOTE: Bulbs are consumables, warranty for three months only.Metal halide light spectrum is mainly for white light output, suitable for germination, stem leaf growth stage.High pressure sodium lamp spectrum mainly yellow light output, apply to blossom and bear fruit stage can also be used for all plant growth stage.High pressure sodium lamp when using a white gold, have high luminous efficiency, less consumption, long life, light color isgood, strong ability to penetrate the fog and trap, the advantages of color temperature 2100 k. Widely used in road, highway,airport, port, dock, station, plaza, street interchange, industrial and mining enterprises, park, garden lighting, and plantcultivation. High color rendering of high pressure sodium lamp is mainly used in the gymnasium, exhibition hall, amusement parks,department stores and hotels and other places lighting.Start the featureHigh pressure sodium lamp starts, in the initial stage is mercury vapor and low-pressure discharge of xenon. At that time, thelight bulb working voltage is very low, the current large; To continue with the discharge process, the arc temperature rise,mercury, sodium vapour pressure is decided by the discharge tube cold end temperature, when the discharge tube cold endtemperature to achieve stability, discharge will be stable, bulb of luminous flux, work voltage, current and power are in normalworking condition. Under normal working conditions, the whole process takes about 10 minutes.Working circuit systemWorking in high pressure sodium lamp circuits in addition to the light bulb, also must be trigger high-pressure sodium lamp insideor outside the trigger high-pressure sodium lamp respectively the corresponding work of circuit, such as light bulbs + electronicballasts can meet the needs of high pressure sodium lamp to work properly.Ask & AnswerBuyers ask: excuse me, the quality of the light bulb?Seller answer: hello, our light bulbs are all domestic exports, in line with national standards, with the FCC, CE certificate ofthe European and American countries. But close to compare him with imported lamp and other brand bulb, the proposal to buyimported bulbs.Buyers ask: excuse me, what brand is this light bulb? Sellers a: hello, general export products packaging is neutral cartons,without brand, so we got the goods are original packing, please note.Buyers ask: can you tell me the bulb is how to achieve the best effect?Seller answer: hello, there is a small suggestion: needs to have two more light bulb, the kiss can make high pressure sodium lampand metal halide lamp and together, effect than single with high-pressure sodium lamp or metal halide lamp.
