Q:What are the characteristics of LED bulb?

Life is more than ten times longer than incandescent, power consumption is 1/2 of ordinary light bulbs, fast response, generally 10-7 - 10-9s, color clear, recognizable performance, good vibration resistance, now the price of LED lamp is relatively high

Q:LED can the bulb be used in the bathroom?

From a long-term perspective is not enough, you can choose a lamp are closed, such as ceiling lamps what, now have special indoor lamps, but you must not use ordinary lamps, because LED lights to the heat at the edge of the open slot or empty, easy water.

Q:LED thread specifications for bulb bulbs?

Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;

Q:How does the LED bulb go with the power?

voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,

Q:Are there any differences between negative ion bulb and LED bulb?

LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.

Q:LED how does the bulb return electricity?

maybe because Make the question clearWhat is the return current?

Q:How to choose the bulb power?

If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.

Q:What are the types of LED bulb?

The LED bulb replacement use convenient, makes this type of products are widely accepted by users by the family, under the same illumination conditions choice to replace the traditional lighting.

Q:How to identify Ic constant current LED bulb?

Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.

Q:What does "A19" mean in LED A19 bulb?

A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm
