Q:How to detect the good and bad of the fluorescent lamp
The most basic and simple method is to test tubes per head of the poles, the poles are conduction description is good didn't burn out, there was a head of the poles impassability (no resistance) is burnt out.
Q:What happens when daylight lights go on
Fluorescent lamp is made of daylight lamp, ballast, consisting of the starter, under normal circumstances fluorescent lamp in the process of start, due to the action of bimetallic strip within the starter, make a sound, "da" start fluorescent work light. The sound is usually the "buzz..." when it's on. Current sound, the sound is due to the ballast assembly is not tight, leaching asphalt technology is bad internal noise caused by loose of silicon steel sheet, and some small factory's products to reduce costs is omitted asphalt link, appear easily in the use of sound.
Q:How do I get the four joints of the LED fluorescent tube
It is impossible to realize that the four joints are actually the lead of the two filament, if the wire and the zero thread are attached to the ends of a filament, the filament is instantly broken. And the lamp is lighted with a core-ballast or electronic ballast. 220V can't be lit.
Q:The ledt8 lamp is used for the light bulb
Generally see you want how much wattage T8 tubes, according to how much wattage to order the lamp bead, generally a lamp bead is 0.5 w, according to the wattage calculate knew how many light bead
Q:I hope my answer will help you
Rotate it, or you can move the tube to the right and try it.I hope my answer will help you.
Q:20wled bulbs are more energy-efficient than 20w fluorescent bulbs
Power electricity consumption is same (same as 10 jins of cotton and 10 jins iron who weigh the same - they are different size). The LED light and fluorescent lamp is different of different life! Also look at the type of LED lights (some brightness nights are bad) don't let vendors and manufacturers cheat!
Q:What are the advantages and differences of the LED panel lights?
From the perspective of the light-emitting LED flat light mainly include side glow and are currently two emitters design, each have advantages and disadvantages of two kinds of light way, is shining on the structure and side shine without guide plate, is the difference between a positive light panel light has the advantage of the same light bead cases higher luminous flux, because the light-emitting panel lamp lights, side shine after reflection of light guide plate need to illuminate, after guide plate has LED to the loss of the luminous flux,
Q:How does the lamp line connect
The one that used to be in the early part of the world, which requires the regenerator to cooperate with the light, is an inductance ballast, and the fluorescent tube now needs to glow without the regenerator. The ballast that doesn't need a regenerator is an electronic ballast. Ask to sell tubes of the owner, they all know and electronic ballast inductance ballasts, now basically eliminated inductance ballasts, everybody understand the electronic ballast is enough. If it is an old lamp, it will meet the inductive ballast. The lamp tube has two feet on each side, and the left and right sides are four feet
Q:Three ordinary fluorescent lamps, now changed to LED fluorescent lamp tube, have influence?
Remove the inductance ballasts and qi, a lot of LED power supply does not support the front with ballast, if adding the ballast, this product may cause permanent damage to the product. Besides, it is energy efficient in itself, why would you add a ballast in front of you? Just cut it off and OK.
Q:How do LED lamp tube install how connection?
If you have a regenerator, you can simply unplug the LED, and if you don't have a regenerator, you need to remove the electronic ballast, which is a hassle
