Q:The difference between the LED lamp

The price Canister light usually have a big (5 inches) in the (4 inches) small (2.5 inch) three. Small between 15 to 20 yuan, the market price of the number of 28-32 yuan between, large-sized between 36 and 48 yuan between. All prices above do not contain light source, of course. Canister light have horizontal and vertical two, flat a little more expensive than the vertical. Is important to note that close exposure lamp generally cannot be used for wool fabric, also can't close any flammable obstacles, otherwise easy to cause fire. Although the lamp power consumption but more in place with its ornament effect. Shoot the light as well as distinctive flavour to the adornment of the five lights cup.

Q:The same power of cob and led lamp which is brighter

General use Taiwan chip COB light efficiency: 65 ~ 80 lm/W, the greater the power light efficiency is lower.

Q:The sitting room how to shoot the light off?

Only take samples of the glass in the middle of the chimney, dial came down hard.

Q:With current meter how to detect the led lamp lights, bad

Can find a lithium battery (or 3 section dry cell in series), series a hundreds of the resistance, to the led lamp bead, try on the reverse, if the light is good, light is not bad

Q:How bright LED globe bulb 5 w? The light is to shoot the light, or like a glow around?

A 5 w LED bulb brightness because of the different vendors lamp bead, the total brightness is different, our company do the white light of the 5 w bulb USES 110 lumens lamp bead

Q:The LED lamp has been flashing, what is going wrong? Original drive 36 to 48 v, output voltage output in a new drive 40-80

Blinking is caused by the stroboscopic, caused by voltage fluctuation. For many reasons, zero line switch fire wrong, drive and inadequate capacitance can cause stroboscopic.

Q:LED to shoot the light is not very bright, or where the flash is broken?

Flash isn't lamp bead bad, this should be a drive and lamp does not match, how much is your driver output volts, current how many, what size of lamp bead, when you load series and form? I can assure you that your lamp voltage than you drive on the output voltage

Q:The 35 w to shoot the light with 3 w LED is not lit, use need not change the transformer?

35 w lamp has two kinds: one kind is 220 volts, no transformer. This cannot be used directly to get dc power LED bulbs

Q:The PAR value of lamps and lanterns is what mean?

PAR photosynthetic active radiation abbreviations: photosynthetically active radiationPAR photosynthetic available radiation, green plants for photosynthesis process, absorption of solar radiation in the chlorophyll in excited state that part of the energy spectrum. About 400 ~ 700 nm wavelength, represented by symbols Qp, units of w/m 2. Photosynthetic active radiation is plant life activities, organic material synthesis and yield formation of energy sources.

Q:The sitting room LED shoot the lamp to be more powerful

Sitting room (should consider its size) LED lamp as a decorative light, only 15 w can, but not commonly used as a lamp, can also according to individual hobby, optional much larger (more verve and high illuminance is often made exciting atmosphere, relaxation of low illumination is easy to build, friendly atmosphere), anyway, not consume too much power
