Q: What's the operation voltage of LED T5 Tube?
A: Its operation voltage is 100-265v ac; generally we provide 110/120v ac for North America, 200-240 v ac for Europe. It is available for specific input voltage such as 277 v ac, 300 v ac or above as request.

 

 

 

Q: For LED T5 Tubes, if one LED fails, will other LEDs fail?
A: No, if one LED fails, the remaining LEDs will still work.

 

 

 

Q: Can I put Ubright™ T5s into the conventional T5 sockets directly?
A: Yes, Ubight™ t5s can be directly put into the conventional t5 sockets. But firstly you need to take off the ballast. For detailed installation information, please refer to the user guide of Ubright™ T5s LED fluorescent light.

 

 

 

Q: Can LED T5 Tubes be linked to each other and what about the maximum quantity in series?
A: Yes. The maximum quantity linked in series is 20 pcs for 1200mm version at 110v ac input; 40 pcs for 600mm version at 110 v ac input; 30 pcs for 1200mm version at 220 v ac input; 60 pcs for 600mm version at 220 v ac input.

 

 

 

Q: Are the FOBSUN LED T5 Tube series dimmable?
A: Yes, EPS version are dimmable, but general versions do not support dimmer.

 

 

 

Q: What's the operation voltage of LED T8 Tube?
A: There are 3 options for operation voltage range, 110/120V AC, 200-277V AC and 100-240V AC.

 

 

 

Q: Can LED T8 Tube be used for outdoor application?
A: No, you can only use it for indoor application for dry environment.

 

 

 

Q: For LED T8 Tubes, if one LED fails, will other LEDs fail?
A: No, if one LED fails, the remaining LEDs will still work.

 

 

 

Q: Can I put Ubright™ T8s into the conventional T8 sockets directly?
A: Yes, Ubight™ T8s can be directly put into the conventional T8sockets. But firstly you need to take off the ballast. For detailed installation information, please refer to the user guide of Ubright™ T8 LED Fluorescent Light.

 

 

 

Q: Are the LED Down Lights series dimmable?
A: Yes, the lamps matched with dimmable driver can be dimmed by traditional ELV dimmers. They will compatible with most dimmers we test.

 

 

 

Q: Which control modes can LED Downlight work in? What's the difference between them?
A: Only the RGB version can be controlled by constant decoder with power supply. It adopts PWM technology.

 

 

 

Q: Does installation need to be finished under power off?
A: Yes, please keep power off until you finish all the installation, or the fuse of driver will be burned.

 

 

 

Q: For LED Downlight, if one LED fails, will other LEDs fail?
A: No, if one LED fails, the remaining LEDs will still work.

 

 

 

Q: Can LED Downlights be linked to each other and what about the maximum quantity in series?
A: There is no limitation for single color down lights.

 

 

 

Q: Do LED bulbs give off heat?
A: LED light bulbs only give off ambient, room temperature heat around the LED itself. One reason LEDs are efficient is due to the low amount of heat around the LED diode junction. To accomplish this efficiency, heatsinks are required to draw heat away from the LED junction. The heatsink may get hot, so be careful not to touch it.

 

 

 

Q: What is the difference between an incandescent bulb and LED?
A: Incandescent creates light by the use of a filament. When power is applied, the filament glows and generates heat - which in turn produces light. LEDs are just the opposite. LEDs create light through a 'cold process'. When power is applied to semiconductors (usually gallium, asenic and phosphorous), they're stimulated by the movement of electrons, which creates photons. Photons are the light that is visibly seen by humans.

 

 

 

Q: Can you dim MR16 LED bulbs?
A: Our LED bulbs are current driven dimmer type voltage variations will not affect them, to dim an LED bulb you would need a current based dimmer. These are called pulse modulators; these devices keep the voltage stable whist switching the current on and off millions of times per second. By adjusting the pulse rate (or gap), this creates a dimming effect and causes no lasting problems for the LED bulb.
