Q:What is a good material of led tube light

Biggest characteristic is that it can keep building decoration of the overall unity and perfect, it developed from the general light source to the popular now LED light source, each has his strong point. Canister light, shoot the light is mainly composed of light bulbs, transformer, lamp cup, buckle. Seize these quality, basic can buy their favorite products. Considerations to choose big manufacturer, big brand, will reduce your choose and buy of trouble. The lamps and lanterns "coat" is generally have a few kinds of sheet metal, die-casting aluminum, aluminum, stainless steel materials. Would be much better, of course, stainless steel, aluminum, nature price is also high. The different material, color difference, according to the household atmosphere mass-tone attune to choose from. The thickness of them decided to price volatility. Transformer, is the heart of the canister light to shoot the light. Although internally, but this is small things, has the absolute weight occupied the whole of the quality of lamps and lanterns, prices, and life.

Q:The ceiling of a ceiling light is of general size

The first is the difference between the different wattage specifications: on the one hand the size of the lamp for 35 w generally has two kinds: The first is a opening, width is 205 * 90, the size of the high of 170; The second is opening, width is 243 * 106, the specifications of the high of 198. And 20 w lamp is generally only one, that is opening, width is 235 multiplied by 106, the specifications of the high of 198. A third type of even 50 w to shoot the light, the size of the gas is opening, width 235 * 106 plus 198.

Q:How much is the LED to shoot the light, color rendering index in general

> 80, we have integrated LED lamp, luminous efficiency is very good, now try shimao riverside Hilton Hotel in nanjing, you can search: the star of the EPC contract energy management, learn more shoots the knowledge well

Q:LED two head lamp lines do not short circuit is not grounded on the total trip what reason?

Because this course has a problem! : insulation does not reach the designated position, there is leakage phenomenon.

Q:What brand of shoot the lamp to LED lamp of choose and buy skills

View the lamp parameters 1. The main parameters of LED lights, especially in high power LED lamp bead has a luminous efficiency and color rendering index, index of the luminous efficiency is 80-100 lm/W, must be greater than 80 LM/W, but the indicators are in growth, to the next year will reach 100-120 LM/W. Color rendering index is 0.8, the index is unnecessary to pursue more than 0.85, unless you are engaged in painting on color high requirements of the job.

Q:LED to shoot the light is not very bright, or where the flash is broken?

Here's why: 1, the voltage is not enough, need to use multimeter to measure voltage conform to shoot the rated voltage. 2, poor contact: check whether the terminal is loose or have foreign body, make its wiring is good. 3, connection error: LED lights must be in accordance with the wiring diagram connection, not in series.

Q:The LED lamp which cheap compared with bovine eye lamp

LED to shoot the light points of smallpox lamp and lamp cup shoots the light, bovine eye lamp, of course, more expensive than the LED ceiling lamp, because the bovine eye lamp shell of a price in more than 8, and ceiling lamp shell a 5 pieces more, single housing price have sent a few pieces

Q:The original old how long pole to shoot the light to LED lights

LED Chinese as the light diode semiconductor has positive and negative May be you take input power + - backwards and thermal conductive glue stick to a high power LED lamp bead need radiator panels mountain or you will burn out

Q:LED to shoot the light, heat sink, aluminum alloy profiles and die casting aluminum radiator which is better?

Even better aluminum profile, material, wall thickness can be thinner, heat dissipation performance is better..
