- 1. Light bulbs made simple
- While there are plenty of news stories and opinions about new light bulb standards and equivalencies, many people are still unsure about what to buy. Following Q&A will help you.
Q: What it is the best replacement for incandescent light bulbs?
A: The only bulb that no longer meets basic efficiency requirements is the 100-watt traditional incandescent. A 100-watt bulb is now required to use no more than 72 watts of electricity. Good replacement choices for your traditional incandescent bulbs are LEDs (light-emitting diodes), CFLs (compact fluorescent lamps) and halogen incandescent bulbs.
Q: Which light bulbs are most energy-efficient and cost-efficient?
A: LEDs are most energy efficient. A single Energy Star-qualified LED light bulb can last up to 25,000 hours and use 75 percent less energy than an incandescent bulb.
Keep in mind that while a traditional incandescent costs only about 50 cents to buy, it costs more than $7 per year to operate. While an LED bulb might cost $20, it should last about 10 years.
Another good choice is Energy Star-qualified CFLs. These bulbs use about 75 percent less energy than standard incandescent bulbs and last eight to 10 times longer.
- 2. What kind of lighting creates a cozy, relaxed feeling?
- This mood generally comes from any light sources fairly close to eye level, such as table lamps, floors lamps, desk lamps and wall sconces mounted at the ceiling, such as chandeliers or close-to-ceiling fixtures, can also provide that comfort feeling when dimmed.

- 3. Tips of how to choose LED down lights?
- Want to buy LED down lights for your new home, or replace exist old lights, and get confused by salesmen in lighting shops. Here, are three tips tell you how to choose LED downlights.
1. Check the brand of leds and encapsulation. As one of main materials of LED downlight, LEDs’ quality is very import. It can decide the lighting’s brightness, lifespan and many other things. Most famous brand is Cree, USA LED chips. Of course, prices are highest. Good and economic one is Epistar, Taiwan. They often do the encapsulation in mainland. There are many other brands as well, Bridgelux, LumiLEDS,, Samsung……
2. Look at Heat Sink(Radiator) LED downlight’s life span is related to the heat sink. If the heat sink is not good, the heat in the lamp can’t be sent out and the life span would be very short. Aluminum is good heat conductivity; good aluminum is good for heat dispensation. And big Heat Sink ("fin" like) LED Downlight also has good heat dispensation qualities.
3. Check the Power Supply(Driver) LEDs is not very easy to get damaged, but the power supply life span is less than that of the LEDs. If the LEDs are damaged, the lamp can be also used. But if anything is wrong with the driver, the lamp will not work, till driver be replaced. So when we choose LED Downlight, we need pay much attention to the driver. And, buy down lights with external driver if possible. Remember these three tips, you won’t get confused.
