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:Non rechargeable LED lamps have a stroboscopic?

Q:Led lamp generally not transformer, why also said some led desk lamp radiation levels
LED desk lamp is actually change pressure device, it's just the name is not called transformer. LED lights need drive power, has permanently flow drive and resistance capacity drive, usually 220 v50hz ac power input. Most LED lights use dedicated driver IC (internal electronic transformer), can supply a set or more sets of LED lights, more convenient and reliable. If the transformer is unqualified, radiation levels.
Q:How to choose the night reading reading lamp
Not use the desk lamp of learning to read, from the point of view of energy saving, LED certainly didn't have to say, but if it is for a long time to read the desk lamp of learning and choice, from the comprehensive health lighting index evaluation, if it were not made to order, if you want to buy the perfect, it had to spend many time and money! As each light source after the revolution, the older generation of light source products because of some outstanding parameters but not completely eliminated, it seems, LED desk lamp light source as won't win all the LED light source.
Q:How long does a charging lamp charge?
Note: if charging desk lamp is newly bought, generally it has a certain power. The electricity used up inside first, and then, it will more protection to the battery.
