Product FAQ

Can MR16 and GU10 LED spotlight work with 110V/220V directly?

MR16 LED spotlight work under 12V voltage, if you want them to work with 110V/220V; you have to use a transformer. Generally, MR16 halogen lamp is always with a transformer working. So you can replace the halogen lamps into LED MR16 bulb directly.   But GU10 LED bulbs can work with 110V/220V directly. You don't need any transformer to help.

Can I control more led downlights with one driver?

It depends. If the power is 1-3W, then a driver can control more lights. but if the power is >4W for example 18w led down lights, It must work with only one driver. For the working mode of exterior driver and down lights, we have 2 solutions:

A.   A driver can work with 1PCS down light.

B.  A driver can work with more down lights. For example, for 1W down lights, you can use a driver to drive 6-8pcs 1W down lights. This way will get your purchase cost down. But if the installation is not allowed, you must use only one driver.


LED Tube T5, T8, T12, what does it mean?

Actually, T stands for the diameter of the LED tube, and each T represents one-eighth inch.  So T8, the most familiar LED tube to us, is one inch (eight times one-eighth inch) in diameter.  As we all know, one inch equals 25.4mm.  Therefore, the diameter of T8 is 25.4mm.  T12 means that the diameter of fluorescent tube is 12 / 8 inches.  T5 obviously means that the diameter of LED tubes is 0.625 inches.
T12 Diameter of 38.1 mm
T10 Diameter of 31.8 mm
T8 diameter of 25.4 mm
T5 diameter of 16 mm
T4 diameter of 12.7 mm


What do “Cool White” and “Warm White” mean, and what is CCT?

The Color Correlated Temperature (CCT) is given in the description of each of our white led bulbs.  The color (CCT) of our white bulbs ranges from a warm yellow white (2700K) to a cool blue white (7000K).
By comparison, a typical incandescent bulb has a CCT of 2800K.  A typical halogen is a bit higher, maybe 3500K.  Daylight white is 4500K and a cool white fluorescent is 6000K or more. 
The human eye adapts to background light so that even a daylight white bulb will look slightly blue in a room illuminated mainly with incandescent bulbs.  Similarly, an incandescent bulb will look very yellow or even orange in midday sunlight.
