Q:Of tubes is said to be good, and some say good leds, which is really good

Incandescent lamp is red light, yellow light is refers to the 2700 k color temperature, most provinces to eyes, fluorescent tubes and LED light is dazzling.

Q:Led energy-saving lamps are easy to break

Don't usually, LED lights so far is one of the longest service life, and environmental protection and energy saving, good friends said out of the blue, to see

Q:LED bulbs can put in the desk lamp of adjustable brightness?

Bad,, it will damage the silicon controlled voltage regulator, The desk lamp of adjustable brightness can only answer the incandescent light bulb

Q:LED desk lamp, the USB interface, security, will the light bulb suddenly blow up

Absolutely safe. The LED is solid, there is no gap, not like a normal light bulb, there is no fry

Q:How many watts appropriate general led desk lamp

Advised to choose a well-known brand LED bulbs, LED bulbs now the price is not expensive,

Q:The led rechargeable lamps useless can also be used for a long time

Is equivalent to ordinary emergency light put a period of time. You can use it's not a problem, if unplug Light is put out that the battery is out of date in a minute. Can replace the battery, or when there is no charging function normal use.

Q:The led lamp charging more than 24 hours have what dangerous?????

1, the desk lamp of authentic qualified, the battery charging protection circuit for battery will not overcharge, adequate electricity stopped. 2, LED desk lamp is with LED (Light Emitting Diode) the desk lamp of the light-emitting Diode as Light source, LED is a solid-state semiconductor devices, it can be directly put DianZhuan into Light. Advantage is the light source direction is good, green environmental protection, long service life.

Q:Energy-saving light bulbs or LED bulb can't use on the dimmer lamp holder?

High quality solutions You can. Dimmer lamp dimming principle, is to use the thyristor (SCR) adjust the conduction Angle, change the alternating current (ac) electricity time to power a light bulb, change in order to achieve the average of the power supply voltage and current, adjust the effect of light intensity. Energy-saving lamps, LED lights, there are the power transformation, all need power supply of alternating current into direct current (dc) first, and then into a high frequency ac (CFL) or dc constant current (leds) to drive a light emitting part.

Q:Led the desk lamp, electronic calendar watch how to adjust?

In normal state, the LCD screen display ALARM logo above the "ALARM", according to "bring" button to open/close to sleep function, the LCD screen above "SNZ" logo will display and not accordingly. In normal state, press "▼" button to open/close function of music appreciation. When open circuit play 7 different music. In normal state, press "SET" key Celsius/Fahrenheit temperature conversion can be realized. In the above calendar clock operation, 1 minute, if no buttons are automatically return to normal state

Q:LED lamp, lens type and light type which good,

How are you First, about the LED lens to make the light more focused, LED by itself cannot be concentrated, so need help on lens. Surface light is simple, LED color performance, add a dustproof lampshade is, sometimes with grind arenaceous chimney, better astigmatism. Besides, desk lamp, desk lamp is the design standard of infinite close to the sun, because artificial forever than nature. So now the LED lamp like stressed without glare No stroboscopic, no radiation it is for this reason, who is more close to the sun, who is better.
