"didn't led save electricity? Why burned them in three months?" – every day in the backstage, you can see the likes of a puddle, so don't shout at the factory, and 90 per cent of the people step on the same pit: buy leds as incandescent lights, but look at the tiles without looking at “light”。
Also 10w, good leds can export 1,000 fluoride, and the difference is only 600 fluoride, so if it's not bright enough, then one more, of course. If you really want to save the electricity, just focus on the unit "lm/w" and get a >90 to pass, >120 is the schoolhouse, forget the box, and turn the side label over and see the real chapter。
Lights short, heat the back. Open it, a thin layer of aluminum shells, squeezing it and deforming it. The heat is suffocated in it, the chips are “high fever” daily and their lifetime is reduced by three quarters. The light is selected first, the thickest course of heat normally spreads with the most heavy watts; then a glance at the interior indicates that the aluminum base sheet is white enough to paint less of thermal silicon. The kitchen, the bathroom, this kind of “high-temperature small room”, which directly selects the plastic bag aluminium plus the waterproof duct money, which is worth ten dollars and lasts two more years。
Drivers are the "kill door." the weakest driver is the electrolytic capacitor, which is already conscientious for 105°c/5,000 hours, with some writing “timeless” and covering large national caps with small fingernails, 8 cents a piece, or 8,000 hours a drum. Not really, remember one thing: it's more than a third of the size of the light and it's basically specious; if it's light like a plastic box, it's right down。
The electrician's page likes to blow "50,000 hours of life" -- that's chip lab data, and the whole lamp runs for 20,000 hours. If you don't want to roll over, you'll have to buy a broken-drive price. The light is not broken, the light is hung up, 15 dollars is replaced by a new drive, and it'll last three years。
Don't let the full spectrum "eye-protective" dizziness go around, with a home-selected color temperature of 4000 k, a high point of ra > 80, a high colour demand, a red bank card at the bottom of the line, a light, a red card, a red card, and a red card. As far as prices are concerned, the 9. 9 nudity light beads have no gold wire, replaced with copper wires, the heat swells and shrinks twice, and will have to be spent at least 25 bucks or more until next year。
In one sentence, the province of led was unwieldy and long. It was decided from the moment it was bought. By flipping the three hard indicators of light, heat dispersion and drive, sunk and dismantled, the pits of “failed electricity short” are largely avoided. Lights are durables, not fast-forwards, and they're worthless。
