Various Christmas party decorations may be selected: Christmas Tree Bell, Christmas candles, Christmas Bell, Christmas gifts, etc. Especially, Xmas LED String Light is the necessity when prepare Christmas ornaments. Why we would like to choose LED Light rather than other kinds of lights? There are some factors:

A: Proper wattage.

The right wattage is important for best results. Don’t even bother with that have less than one watt of power. Usually it is best to purchase three-to-five watt LED lights. There are many brands of Warm White LED Spot Light, LED Strip you can find for this wattage category.

B: Long life span.

Good, reputable, high-power LED lights will generally have a true operative lifespan of 50,000-100,000 hours of usage. This number can drop significantly if the temperature is not maintained, however.

C: Good heat management.

It is important to have lights that include good heat sinks and cooling fans. An overheated Christmas LED light won’t last long.

D: Proper power circuit.

When it comes to powering a LED Light it is important that it comes with a good constant-current driver circuit. This is roughly equivalent to the ballast found on other types of lights, and converts electricity from AC to DC. As its name implies, it offers constant electrical current despite changes in the LED light’s voltage over time and across various temperatures. If a driver isn’t constant-current, then the current to the light will vary in response to voltage increase or decrease, which can drastically cut the lifetime of the bulb. When purchasing your light, look for the term “constant current" in regards to the driver circuit. This will provide a non-fluctuating and appropriate power level for the lights amid changing temperatures and voltage needs.

Environmentally conscious people that enjoy growing plants indoors will find that doing so with these lights will provide ample extra lighting for a fraction of the energy cost. These types of lights do not need to be changed nearly as often as HID or HPS style lighting, as long as the overall temperature of the grow light does not exceed the manufacturer’s recommended specifications.more info :www.hofoled.com
