 How to Install LED Commercial Downlight
Q1: Why the beam angle of your 4inch commercial downlight is too small?
A1: If you think the 30degree in not enough, we also can make frosted lens, it can reach to 40-45degree.

Q2: What would you do if downlight fails within warranty period? 
A2: If evidenced that failure is due to quality issue, we will send customer a new one for replacement.

Q3: What kind of lamps do the commercial downlight replace?
A3: CFL, HID, Metal halide lamp or incandescent.

Q4:  Is your commercial downlight DLC listed?
A4: Downlight is regulated to Energy Star. DLC and Energy Star are two categories of energy   saving certificates, one product can only obtain either of them.

Q5: What's the difference between AC dimmable and DC dimmable?
A5: The obvious difference is the difference of working voltage. AC120V should AC dimmable, 100-277V should DC dimmable.

Q6: Why commercial downlights are more  expensive than residential downlights?
A6: Because we use CREE chip, YG driver (cooper lighting's driver manufactuer). The watts is more higher and  less marketing competion. OKT Lighting is only one and first one who can produce this commercial downlight from China.

Q7: Do you sell can (housing)?
A7: No, we do not. But we can recommend a reliable housing factory for you. (OMD, Liteharbor)

Q8: Do you have smaller package for downlight, the shipping cost is too much.
A8: No, we don't have. It is our standard package. The shipping cost is cheap if ship by sea.

Q9: Do you offer mounting brackets as well?
A9: Yes, we can supply mounting frame.

Q10: What’s the difference between new version and old version downlight?
A10: We add one lens in new version downlight,so the light will be soft and even,there are 4” and 10” downlights more in the new version.
