Q:What is the category of LED bulbs, T6, T8 or whatever?
In practical use, thin lamp tube is easy to conceal, use the occasion also be flexible, this is why T5, T4 light tube to get the reason that stylist people favour However, the more difficult the tube is, the more difficult it will be, so when it comes to the T5, the electronic ballast must be used to start the lamp. In order to save costs, T5, T4 of miniature stents has been adopted in the form of sale, mini space is the ballast in bracket, the efficiency and quality of the ballast are generally not very good, should lead to very high efficiency tubes as conventional T8 tubes instead of bright, life can be a little discount. Still, the lure of the tube is still strong, and the T5 and T4 bulbs are selling more and more. The difference between T5 and T4: The theory should be that T4 is efficient, but because of the quality of the ballast, many T4 is not as bright as T5. Life and stability are different, T4 is not as mature as T5, so life expectancy is slightly shorter than T5
Q:Put on the new light bulb, why the lamp still not bright
If there is a problem in the ballast itself, if the lamp filament of the inductor is red but can not be activated, most of the regenerator short-circuit damage.
Q:Is the normal daylight tube replaced by an LED line
Step 1: use a screwdriver and a pliers to disconnect the ballast from the wire. But my home is the sun lamp base of zhengtai, the quality is too good, it took 10 years. I didn't even get down to the ballast, which was stuck in a full thick iron base, so I disconnected the wire. The wire that disconnects from the ballast is sure to have two heads, just to disconnect the connection. There is a lot of direct skewers of black tape, some of which use that connector and screw the two wires together. It's the same thing. This is the connector that is used in this case. Disconnect the regenerator, remove the wire and then rewire the two broken wires together and attach the black tape (which is the insulating tape). Put the base back to the original. Install the fluorescent tube, and remember to place the head of the European logo on the base of the current. And when you put it in place, it's going to be OK.
Q:Excuse me, the lamp in the sitting room lamp is carried good or the lamp tube is good
The experience that USES me to do a dozen years to do lamps and lanterns, the best is to adopt T5 lamp tube, its advantage is: the life is long, and bright. The small beads in the lamp band are easily broken, although the price is cheaper, but it is more difficult to change frequently. In the end, a lot of guests will change it.
Q:Does daylight bulbs damage electronic lamp heads?
Will you get the power wrong? Maybe there's some protection on the lamp that the developer has lost, if you're the new one, you're going to go to the dealership.
Q:The various specifications of LED fluorescent tubes
LED daylight lamp tube routine parameters: 1, fluorescent lamp specifications: T8, T5, T4 difference and length of tubes, power description: commonly used with T8 and T5 fluorescent lamp specification, T4 lamp, with three tubes of a set of usually is T5 tube, commonly used fluorescent lamp specifications have T10, T12 long ago. "T", represents the "Tube", said the Tube, the Numbers behind the T Tube diameter, T8 is eight "T", a "T" is 1/8 of an inch, one inch is equal to 25.4 mm, then each of the "T" is 25.4 present 8 = 3.175 mm
Q:Why does the led fluorescent tube have water vapour in it? What causes it?
LED fluorescent lamp tube USES the LED lamp bead, the lamp bead electricity, send out heat big, if sealing sex is not very good, have air enters, enter, can produce vapor.
Q:Why do LED bulbs have stroboscopic frequency? The camera
There is a difference between the eye and the camera. This is caused by the ripple current, and this general customer will be required. It will be down to 10%
Q:How to connect the power supply when the LED lamp is energized?
The power supply is not positive and negative, and the power supply can only work under the dc environment. Normally bought LED lamp tube has built-in power, can be used directly in the lamp holder, but should be careful to remove the regenerator, short connect ballast. You can also go to LED918 for me.
Q:A 30-watt light bulb can be used for a change of LED lamp
Of course you don't rule out that the lamp you bought is bad. I hope I can help you.
