Individual led lights are not lit

Individual led lights are not lit

The led tube lights incorporate a “constant-current” circuit design; meaning single led lights operate independently from other leds on the circuit board. a few individual unlit led lights will not greatly impact the overall light output and do not affect the other leds on the board. 

OBS offer 5 years warranty, when first installed, has more than 5 individual leds that are not lit, please contact with us.

LED tube light is blinking?

LED tube light is blinking

a.  Bad contact 
ensure that the contact points on both sides of the fluorescent bracket have a good connection to the contacts on the end of the led tube light. gently rotate the led tube light or adjust the lamp stand spacing.

b.  input voltages are wrong 
Please confirm that the voltage used under right scope. if ballast inside lamp holder, please make sure the voltage output of ballast match that of led tubes.

c  damaged during transport or handling 
Gently shake the led tube and listen for any rattling sounds. if there is, it may indicate that the tube has been damaged during transit or handling.

LED tube light is not working after installation.

LED tube light is not working after installation.

a. Confirm that power is switched on. 
If required, use a multimeter to confirm that power is running to the inputs and that it is the correct voltage.

b. Bad contact 
Ensure that the contact points on both sides of the fluorescent bracket have a good connection to the contacts on the end of the led tube light. gently rotate the led tube light or adjust the lamp stand spacing.

c. Damaged during transport or handling 
Gently shake the led tube and listen for any rattling sounds. if there is, it may indicate that the tube has been damaged during transit or handling.

Why LED Tube price difference?

Today LED Tube market price of the so-called changeable.

      Take LED Tube examples. 1.2 m the T8 18WLED in fluorescent light, it was sold for the price of $7, and some company was sold for $66, why not so much price volatility? Here I will explain it.

Price different reasons:

First, the radiator: radiator cooling speed of decision lamp beads light fades.

Second, the power drive: power-driven quality determines the overall life of the lamp beads, lamp beads almost does not matter, but drive with low-grade, LED fluorescent tube can easily be burned. Lamp beads by differential is light fades faster than normal.

Third, lamp beads: Chip differences, different packaging skills determines their different prices, many customers concerned about the specifications of lamp beads 3528 or 3014, in fact, really should be concerned about is the size of the chip and manufacturers.

      Is caused by more than a few reasons to order gap between big and small, probably you do not believe, well I use practical examples to example. 3528 beads cheap dime a 288 is $5, the better Taiwan wafer lamp beads is $2.3, the gap 14.4 $2.8; the cheap driver is $2.3 a, isolated power supply is $4.6, the inexpensive $ 26.5. We know why the price gap, right?
