Q:I have LED lights on fluorescent lamp tubes, and I have tested five times a dc
Let's say a light bead is working at 3v voltage and the current is 300ma. To get it to 3.1 volts, the current can reach 400ma. 220v market volatility is large (200-250) sometimes higher. At the very least, you need to add resistance.
Q:Can a fluorescent lamp electronic ballast be powered by an led
Himself is the home of all of the fluorescent lamp, mirror lamp, absorb dome light to all leds, principle is to change the electronic ballast to electronic transformer, and a simple rectifier filter is a dc voltage source, the string of a current limiting resistor can light up the led,
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:Led lamp tube t8 good or t5 good
The specification of fluorescent lamp is the diameter of tube, length. Look at your lighting requirements, T8 pipe size, of course, the light effect will be better, the same length of lamp tube T8 will be more than twice as bright as T5, and the brightness is much better. The quality of the lamp is not so good at present. The main view is lamp tube with light, electric power and heat dissipation processing.
Q:Three ordinary fluorescent lamps, now changed to LED fluorescent lamp tube, have influence?
Yes, inductance connection to the tubes of the rectifier takes inductance, but LED bulb as long as the end of the power supply directly to access to the power supply is ok (after which two feet to look at the instruction of GeChang)
Q:Can the LED tube be installed as a general lamp holder? It won't burn easily
Not necessarily, if you buy the lamp belongs to universal, some tubes into line is at one end of the tubes, so again after confirm the specification on the connection mode, when compared with the ordinary lamp holder, if can be general, will not burn.
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:Can the T5 light tube be free of ballast?
The lamp tube wants to start with high voltage small current, again in low electricity to run down work, the ballast is two kinds of effect. If you connect directly, you will burn the filament and not light.
Q:The difference between an LED tube and a daylight lamp
Traditional fluorescent lamps generally cannot choose color temperature, and color. LED bulbs have a choice.
Q:Is there a greater value in switching from a normal daylight lamp to an LED energy-saving lamp?
The main consideration is commercial or civilian The use of civilian use is lower than that of commercial electricity Business is more appropriate The details are also calculated according to different scenarios
