Q:Excuse me how many W LED lamp appropriate gallery

Color rendering index suggested that more than 80 Ribbon star lighting technology

Q:With current meter how to detect the led lamp lights, bad

Can find a lithium battery (or 3 section dry cell in series), series a hundreds of the resistance, to the led lamp bead, try on the reverse, if the light is good, light is not bad

Q:The LED is low voltage and high pressure

Don't blindly pick, check whether it is capacitance step-down circuit. Details refer to the China electronic DIY home of the relevant information

Q:The difference between led grille lamp and dared light

Dared light source of light is a small lamp bead, grille lamp light source is T5 and T8 tubes.

Q:Cob lamp and led lamp that electricity consumption big?

The LED lamp advantages: 1. LED lamp use in low voltage direct current (dc) drive: has the advantages of small load, interference of low use environmental requirements. 2. The LED lamp can well control light spectrum, which can effectively used in the museum and gallery in local or accent lighting. 3. The luminous directivity of LED to shoot the light is very strong: brightness attenuation is much lower than traditional light, LED lamp price. 4. LED lamp very fast response time: in microsecond, as long as the switch is opened, will soon be bright, there will be no delay and flicker phenomenon. 5. The LED light that shoots the light energy concentration is very high: focused on smaller wavelength window, high purity. 6. Life is very long, generally between 50000-100000 hours, because the LED is a semiconductor device, even frequent switch, also won't affect the service life. 7. Good environmental protection, LED to shoot the light in the process of production don't add "mercury", also do not need air, do not need glass shell, good impact resistance, good shock resistance, invulnerability to breakage and facilitate transportation, very green, known as "green energy", the LED lamp price. 8. Energy saving, LED to shoot the light spectrum of almost all concentrated in the visible light spectrum, the luminous efficiency of up to 80 ~ 90%. 4/5 people think commonly, energy-saving lamps save energy is a great invention, but the LED lamp energy-saving 1/2 than energy-saving lamps, this is a solid light source is more great reform.

Q:LED to shoot the light on when why?

May be your circuit of instability A poor contact.If you heat didn't handle, lead to protect the chip

Q:The 35 w to shoot the light with 3 w LED is not lit, use need not change the transformer?

35 w lamp has two kinds: one kind is 220 volts, no transformer. This cannot be used directly to get dc power LED bulbs

Q:The classification of the LED lights

This should is to shoot the light, only the more unique diamond lens

Q:Smallpox lamp is max25w LED power rating, is 25 watts

Yeah, you got a lot of light? If it is 25 w it should be very bright!

Q:Electric rail, shoot the light will be bright

Is the power of 300 w, it is 300 w. Part and after electric energy into light energy transformed into heat energy. The LED conversion rates are higher. You should be to want to ask, what's the equivalent of 300 W leds W bulb, or fluorescent lamp?
