Q:How much LED 150W downlight spiral energy-saving lamp replacement
I do the lighting! First, where do you use 150W energy saving lights? With 150W energy saving lamps will only be used in industrial and mining lights, indoor general lighting is unreasonable. Simple answer to you, the general energy-saving lamp (60ml/W) lumen is led (120ml/W) half, that is, 150W energy saving, with 75W LED can replace brightness!
Q:LED downlight downlight and how to distinguish?
LED lamp is a light source of a yellow dot, dot diameter of about one centimeter. The rear is a cylindrical aluminum radiator similar to a computer CPU radiator (and some have no, and no radiator is of poor quality)General downlight general light source is a small bulb, a bowl shaped reflector.The two lamps are easy to distinguish.
Q:LED downlight, embedded lamps, lamp tube and difference?
At present, these concepts are vague and can be mixed up in the industry
Q:Excuse me, how many different sizes for LED lamp lumens
If we assume power 5W 4 inch downlight case, assuming optical efficiency is 100LM/W, 4 inch downlight ideal luminous flux of 500LM, is on the wreck. The transparent cover is about 400 of the LM, if it is other material non transparent light cover would be lower, probably only more than 300 LM
Q:Home LED lighting downlight is broken, want to change themselves, I would like to ask how to remove ah? Where do you start?
Pull a downward edge can be pulled out, which is two spring clip. Check the porcelain plug for disconnection or poor contact. If not, you can judge that the LED is broken and the lamp shop is on sale
Q:How much is the general 15WLED lamp luminous flux.
Look at the product parameters, and if it's done with a single 1W, it's probably around 1600LM,
Q:What is the difference between the LED and the LED lamp ceiling lamp
In appearance, it's just a different shape.If from the use point of view, led ceiling lamp has environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on, it is widely used in urban road lighting.LED downlight belongs to directional lighting lamps', it only on the 'vertical' surface to the light beam angle belongs to light, light is concentrated, contrasting. More prominent objects, higher lumen, but also set off a quiet atmosphere of the environment.Led downlight characteristics: architectural decoration of the whole system and a 'perfect' does not break bad lighting settings, light hidden building interior decoration, the light source is not exposed, no glare, the visual effect is soft and uniform.
Q:The opening 7, 5 cm height of the LED lamp, home decoration into the floor with fear of hydrochlorothiazide
Let the master in the wiring on the lamp to think about the way, I suggest you go online to see, in mind, or else you worry
Q:LED lamp power off why would light up
The distribution of capacitor connected switch contacts of parallel line formation (originally existed), after turning off the switch can still trace by alternating currentYou used a small light source lamp power LED lamp (mA current to shimmer)The combined effect of the above.
Q:Steam more business bathroom bath with what LED lamp?
LED is the heat source, and belongs to the heat dissipation lamp lamp, the panel is also very hot, and the hot surface is not fog, dew condensation, which is the basic common sense, so do you have anything to worry about. The so-called "anti fog lamp" on the Internet is nothing more than the high sealing degree of the panel and the soft light emitted by the semi transparent panel.
