6) T8 LED tube light details



Q: Nearly all T8 LED tube light are the same exterior,how to tell quality?

A: Price and exterior.


Though LED lighting products are with same or similar exterior,due to raw material cost difference is big,poor quality are all poor housing exterior with short FINs and light weight.So prices are also low.


Besides,the driver exterior is also low-end with poor IC,MOS and capacitances.


Q: Does T8 LED tube light really have 50,000 hours lifespan?

A: 50,000 or longer lifespan is only theroy from lab test.But due to working enviroments are different from in lab,actual lifespan is only  <=30,000hours.


Especially for LED high bays and LED floods,the power is very huge,and lots of heat cause LEDs junction temperature very high.And light decay will be higher than low power LED products.



Our LED tubes are in the market over 7 years,and according to feedbacks from our clients,nearly no faluire in 4-5 years.


Q: For same power,why different suppliers with different brightness?

A: Different chips,or same chip but different brightness version.The brightness will be different.But for same chip and same brightness version,the brightness will be slight difference.But please make clear the difference between LEDs and lamp fixture.


For example,18W LED tube light,LEDs brightness is 2200lm,true fixture brightness is only 1700-1900lm(even lower).but many suppliers type 2200lm in their data sheet,please note this.


Q: What is CRI?

A: CRI is a figure which feedback the real objects colors.Higher CRI with higher cost.For LED tubes,the CRI is mostly 70-75Ra,and 80Ra with higher cost.But there are some suppliers write a high data to attract clients,please note.


Q: What is PF and efficiency?

A: PF and efficiency is to feedback the driver electrical performance.Higher PF and efficiency with higher cost.


Q: Is there cheap shipping cost to import to our country?

A: For small order,express will be best.And for bulk order,sea ship way is best but take much time.


For urgent orders,we suggest via air to airport plus our ship partner send to your door.


Q: Can we get support if we have our own market position?

A: Please inform us your detailed mind on your market demand,we will discuss and propose helpful suggestion for you,to find the best solution for you.


For any further information,please feel free to contact,we will send you PDF document to show full issues you care on LED business.

Q:How to choose daylight lamp? What is the light bulb specification?
Characteristics of the fluorescent lamp, lamp began to ignite need a high voltage, normal light allows only by small current, the voltage is lower than the voltage at the ends of the tube. On both ends of the fluorescent tube is equipped with a filament, the glass tube inner surface coated with a thin layer of phosphor, tube is pumped into the vacuum after the 10-3-10-4 mm hg, filled with a small amount of inert gas, at the same time also injection liquid water trace amounts of silver. Is a core inductance coil inductance ballast, the inductance of the nature is when the current in the coil change, will cause the change of the magnetic flux in coil, thus produce inductive electromotive force, the direction and the current in the opposite direction, thus hindering the current changes.
Q:How does the lamp line connect
If the lamp is ordinary lamp, that is the kind of tubes, tube wall coated with phosphor is need ballast, if it is a led lamp, does not need ballast, later I'll detail
Q:What is the reason for the movement of light in the tube
Lamp tube problem, get a hot towel tube to wipe, sometimes can solve.
Q:An electric power saving device installed on an old-fashioned daylight lamp tube
Make a voice-controlled circuit to control the power switch.I hope my answer will help you.
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:Help me see the yellow on the left side of the LED fluorescent lamp
The yellow one is the gauge capacitor, the first element on the left is the NTC resistor, the third component is the inductance, and the two components behind the inductance are the electrolytic capacitors,
Q:How does the LED fluorescent lamp tube be fixed with the aluminum plate in the tube?
The person thinks still silicon fat + screw, but the screw is not easy to install, do not know the big man has the gao zhao4?
Q:What lamps and lanterns are used to save the LED fluorescent lamp
The supermarket illuminates LED fluorescent lamp tube, LED grid lamp, LED bulb lamp/LED bulb bubble lamp is the most province electricity.
Q:Why is the household daylight lamp attached to the battery?
No, there aren't more than 40 fluorescent lights. Anything else.How big is the tube and the battery? There is nothing else.
Q:A set of lamps and lanterns
Led tube specifications are t5 and t8, with a length of 0.6, 0.9, and 1.2 meters. It's also 1.5 meters. Led bulbs are now priced from a dozen to seventy eight, and different quality prices are different.
