Friendly reminder:
Many sellers use the banner of LED bulbs to encourage consumers to buy them at very low prices. Here is a description of the difference between LED bulbs and ordinary bulbs to the majority of buyers:
Difference 1: LED is called“Secondary light-emitting tube”, Is a kind of crystal; ordinary bulb is a kind of glass with luminous lines added in it
Difference 2: The LED bulb component is crystal, high temperature resistant, and will not be hot at all when used continuously for a long time; the component of ordinary bulbs is glass, and it is easy to get hot when used continuously for a long time and cause the bulb to not light up.
Difference three: LED bulbs have good condensing properties, the condensing is round, and the condensing light is uniform; ordinary bulbs are generally concentrating, and the condensing is irregularly round(Mostly elliptical), Condensation is uneven, relatively scattered, easy to astigmatize
Difference 4: LED is super durable. It’s okay to accidentally use the light bulb and fall to the ground. The light bulb is intact; ordinary light bulbs are not durable enough, and they are basically broken when they fall on the ground.
Difference 5: As a newly developed energy product, LED is very energy-saving and consumes very low power; ordinary light bulbs, as an older generation consumer product, consume a lot of power. The two batteries with the same power are installed in the torch of the LED light bulb and the ordinary light bulb. On the flashlight, the use time is obvious.
It can be seen that there is a fundamental difference between LED bulbs and ordinary bulbs, and they are easy to distinguish. Buyers are expected to choose carefully when buying.
To distinguish with the naked eye, LEDs are crystals and do not contain impurities; there are 2 light-emitting circuits inside ordinary bulbs.
Features of our LED pen light:Small aperture, low power consumption, reliable qualityExperimental test by factory inspector: 2 ordinary No. 7 carbon batteries can keep on for 15 days, and the LED bulb does not generate heat. Under the same conditions, ordinary light bulbs can only last for 2 hours, and the light tube is hot and the light bulb goes out.
