Many customers want to get the lowest price from the factory's products, even don't consider the quality of goods, BUT, as a professional manufacturer of LED, (HOYOL)we have to say, the price we sent to you is worth of the goods , our filament bulb lamp has been sticking to use sapphire substrate , and dare to ask how many manufacturers doing this now?
Our product engineer give a fact that: 0.0625 W low-power chips, with 30 mA drive, brightness can also achieve approximately 9-12 lm (using the chip for: 16 18, 9, 10 * 10 * * 21 mil, 10 * 23 mil), but the brightness is pushed up by current, not the normal work of the brightness chip, these a few chips, strictly speaking, only can use the top 20 mA driver, but now some bad manufacturer for 30 mA driver, is a kind of very irresponsible, they think 2835/301 4 stents better heat dissipation, they are not afraid! where is LED light failure? Then after Lumens depreciation, where is the factory ? Are not clear! Can you save a lot cost?
Hope we all think it twice!
