This product tag HPS600W of 600 w immoderate stress sodium lamp1000whigh strain sodium lamp product introduction;1. The diameter of 67 mm, 380 mm in length, soft middle size is 240 mm. 220v voltage, frequency of 60 hz. Luminous flux 55000 lm. The provider lifetime of 24000 hours5. The temperature coefficient of 2100 k. This product tag HPS1000W of a thousand w high stress sodium lampNOTE: Bulbs are consumables, guarantee for 3 months only halide tender spectrum is particularly for white light output, suitable for germination, stem leaf advancement degree pressure sodium lamp spectrum mainly yellow soft output, follow to blossom and undergo fruit stage can be used for all plant development stageHigh strain sodium lamp when utilizing a white gold, have high luminous efficiency, less consumption, lengthy life, mild coloration is good, stable skill to penetrate the fog and trap, the benefits of color temperature 2100 k. Widely utilized in road, highway, airport, port, dock, station, plaza, road interchange, commercial and mining enterprises, park, garden lighting, and plant cultivation. High coloration rendering of high stress sodium lamp is very used in the gymnasium, exhibition hall, amusement parks, shops and motels and diverse places lighting the featureHigh strain sodium lamp starts, in the initial degree is mercury vapor and low-pressure discharge of xenon. At that time, the light bulb operating voltage is terribly low, the current large; To continue with the discharge process, the arc temperature rise, mercury, sodium vapour stress depends on way of the discharge tube bloodless finish temperature, when the release tube cold finish temperature to attain stability, discharge may be stable, bulb of luminous flux, work voltage, current and tool are in ordinary working condition. Under normal working conditions, the whole activity takes about 10 mins circuit systemWorking in immoderate strain sodium lamp circuits besides the sunshine bulb, additionally should be set off high-pressure sodium lamp within or exterior the trigger high-pressure sodium lamp respectively the corresponding paintings of circuit, similar to gentle bulbs + digital ballasts can meet the purposes of high pressure sodium lamp to work properly AnswerBuyers ask: excuse me, the conventional of the light bulb?Seller answer: hello, our gentle bulbs are all domestic exports, in line with national standards, with the FCC, CE certificates of the European and American countries. But close to examine him with imported lamp and various model bulb, the proposal to purchase imported bulbs ask: excuse me, what brand is that this gentle bulb? Sellers a: hello, general export item packaging is neutral cartons, with out brand, so we acquired the goods are original packing, please observe ask: are you able to tell me the bulb is easy obtain the best effect?Seller answer: hello, there's a small suggestion: must have two extra gentle bulb, the kiss could make excessive strain sodium lamp and metallic halide lamp and together, influence than single with high-pressure sodium lamp or metallic halide lamp.
