The 5W directional downlight is made of 5pcs of high brightness 1Watt LED chips, with aluminum lamp body and the superior thermal design, it equals to 45w conventional incandescent, saving much energy, exchanging heat rapid, and environmental friendly.
Because it’s directional, you can designate its lighting position according to your demand even if you have installed it in the ceiling.
With Non-dimmable and dimmable version for choosing, you can specified your light need as your please. The dimmable downlight is compatible with the incandescent dimmer, so no change needs to make to the pre-existing circuit.
