Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!

Plastic bulb lamp, I have done it myself, this gadget specializes in low-end market, it is recommended not to use, used well, used for a long time, used poorly, minutes of effort have to hang.

Q:LED bulb w can replace 40W incandescent lamp

D lamp lumen value is ordinary incandescent lamp about 3 times, but LED ball bubble mask transmittance should be based on material, can use 10W or so LED acrylic mask ball bubble instead. Because I received a similar customer complaint, 7W's LED light bulb was replaced with an 20W energy-saving lamp, which was not bright enough.

Q:Ordinary lamp LED bulb can?

As long as the inside of the interface is the same, for example, the E27 interface (ordinary spiral, that can be installed energy-saving lamps) installed there is no problem, LED bulb is now a lot of 110V-220V high voltage power supply, so the stability is very strong, the key is to save electricity, saving seventy percent than the energy-saving lamp, no effect, ease of use.

Q:Can the bulb's true life reach 30000~50000 by LED?

According to the current LED manufacturing technology, LED bulb has a lifetime of up to 30000 hours.

Q:How does the LED bulb go with the power?

Online shopping search: LED driver power 12-18w, the key to see the current must be 300mA, covering the 36V

Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?

Heat conductive adhesive is best.Heat conductive adhesive, also known as thermal conductive silica gel. Organic silica gel as the main body, adding fillers, thermal conductive materials and other polymer materials, mixed by silica gel, has better thermal conductivity, electrical insulation performance, widely used in electronic components. Also known as: thermal silica, silicone rubber, silicone heat, thermal conductivity of silicone. The accelerator is used to solidify a transformer, transistor, and other heating elements onto a printed circuit board assembly or radiator

Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!

Sandblasting can be transparent, light is not dazzling,But will still see the light...

Q:What's the reason why LED bulb gets a lot of heat?
