Q:How much is the ballast of the fluorescent tube coming out

The fluorescent lamp ballast is not to be understood by the idea of the current when it is activated in the lamp tube. The lamp tube of different wattage matches the current of the ballast of different current and the current is too bright or hard to start. Inductance ballasts, for example from 8 w15w20w30w40w when it in tubes without ballast between the output voltage and the zero line is power electricity after being connected in good tubes start according to the voltage at the ends of the lamp power different lamp in 80-110 - v, about 40 w at the ends of the tube voltage 110 v. Electronic ballast is the principle of the second inversion of high frequency oscillation. The output power is achieved by the size of the current supplied by the booster coil. The single-strand wire of the 13W booster coil is made, 25W with a two-ply line of 36W with 3 strands of 55W with 7 strands of gauze, the more power the larger the need of the current. Because of using ordinary multimeter is not suitable for testing the high frequency alternating current (ac) in maintenance electronic ballast can be ignored when the output voltage and to detect components mainly including tubes.

Q:A 30-watt light bulb can be used for a change of LED lamp

The fluorescent lamp bracket some trouble, generally in the power of the led lamp is generally in 18 w 9 w, 600, 36 w in 18 w, 1200 long, 30 w words should be in 12 or 15 w, do you want to make sure the tube length.

Q:Use LED fluorescent lamp tube to replace, the line of original daylight-tube seat should be refitted

So old ballast, the ballast uninstalled, directly to the card on the two old fluorescent lamp wire short respectively, and then to the outside power, install the LED fluorescent lamp with respect to OK

Q:If the body is accidentally broken, will it be electrocuted?

It's possible to do it but just don't touch the tungsten in it. If it's on, your body will burn!

Q:How long does the energy-saving daylight lamp tube change?

Fluorescent lamp use time is long, the brightness is low is normal [because of the efficiency of fluorescent powder is reduced, cause lamp tube brightness drops]. The general store is not convenient to replace at any time, it is better to replace it at once. If you increase the density of the light, the light efficiency of the tube will not increase much, and the energy will increase with the opening of the tube, a little waste. A one-time change is a lot of input and a lot of it is compared to the actual computation.

Q:Is there any LED fluorescent lamp that can be used for more than five years?

If it is lit 24 hours a day, leds will not work. The lamp tube is the built-in power seal belt, the heat is not good the life span is long. But it can be custom-made, use the anti-sulphur lamp bead without cover type design, heat dissipation should be done particularly well, the external constant current power supply, the current hits 50% rated current. Five years is no problem.

Q:How does the traditional daylight lamp tube replace the LED light tube?

The regenerator will be removed with the rectifier.I hope my answer is useful to you.

Q:The ordinary fluorescent lamp in the home is on the Internet say to remove the hui, the ballast part is short, put on LED lamp tube, can connect to change 3 lamp tube not bright?

Tear down, the starter of the ballast two wires together is short circuit, and then mount LED bulb, then spin the tubes card in place, above if no problem, so there is no possibility of three light tube is not bright.

Q:Does the power drop when the lamp of fluorescent lamp declines

Because daylight through the electric current is determined by the current limit (ballast), so the lamp how basic will not affect the size of the total current, so what it consumed power will not change.

Q:Brightness, longevity The current led lighting tube is 90-100lm/watt, and the life span is more than 20,000 hours, and the chips and power supply should be paid attention to. We adopt a 3-ampere, long power supply to ensure the quality of the lamp.
