Q:Led to shoot the light, the 12 v transformer and transformer can general ordinary lamp?

Transformer are interchangeable, but LED is a dc power supply, if the pressure after the bridge rectifier, more than 12 v, also need to consider the LED string and method and current limiting resistor.

Q:Aquatic plants cylinder light can use LED lamp?

Current leds are not suitable for plants, plants or a professional grass lamp is best, followed by the philips 865 color temperature (6500 k) and 6500 (color temperature 4000 k) series of tubes.

Q:The 4 w LED shoot the light, can make the lamp of the study? Reading a book with

no Is too small After a long time eyes will be very uncomfortable

Q:Household LED lamp directly on the ceiling above the glass, glass temperature is higher, matter?

LED lamp life is directly related to working temperature, high temperature must influence life, such as lamp bead light early failure, damage to the drive, and so on, so the LED heat dissipation has been LED lighting to solve big problems.

Q:LED lamp PAR30 - more than 40 w hours kilowatt-hour

Built-in inside have a small fan, increase the rate of a damage of instability. Increase the rate of damage.

Q:What kinds of leds are included?

LED to shoot the light is roughly including LED lamp cup, LED ceiling lamp, LED downlight etc, PAR lamps and the LED lamp, LED bulb is not big. Because the lamps and lanterns of LED lamp is refers to the condenser, and the ball bubble lamp is glistening divergence. Former friends right!

Q:How to distinguish the stand or fall of the LED lamp

LED lamp cent two kinds of low pressure, high pressure, consumers had better choose low voltage lamp, its long service life, high light efficiency. Shoot the light efficiency of high and low to power factor, power factor, the greater the photosynthetic efficiency, the better, the power factor of ordinary lamp at around 0.5, the price is cheap, high-quality shoots the lamp power factor can achieve 0.99, the price is a bit expensive. Shoot the generally used to strengthen the lighting on the trim, general is embedded in the ceiling or wall, LED to shoot the light work generally have a higher temperature, so set to buy the high quality product, otherwise there will be a security risk

Q:What do you need for homemade LED lights

：Can be accomplished within 15 meters of LED irradiation, 50-100 meters even traditional project-light lamp all cannot do it

Q:The luminous flux LED to shoot the light, technical parameters, MR16 GU10, chips and other parameters

LED shoot the light cup MR16 voltage: 12 v, 3 x1w flux: 240-300 LM this is to see what is the single light bead chip size to LM, like 45 ml 112 LM chips do no problem, then flux have 312 LM, GU10 voltage can be done as required.

Q:What is the difference between LED ceiling lamp and LED downlight

Is vertical illuminate the canister light, shoot the light as the ceiling.
