Q: How many lumens is the T5 bulb of 18W: Look like you do with t5 example, t5 strengths, now, now is from inductance rectifier to improve the electronic rectifier, higher efficiency, lamp lumens not only meet the even more than the national standard, reached about 90 lumens. And t5 is more efficient!

Q: The difference between the Ledt5 lamp and the temperature 3000k and 2700k: As it turns out, there's a lot of difference between 300 k in low color temperature. 2700K is warm and yellow and 3000K is warm and white. The latter is brighter, but the former is warmer!

Q: Where is the very thin daylight lamp usually bought?: There's no need for a lamp slot for the hardware store. Because it's on the lights. Most of them are screwed. The light bulb of a home. You don't need to buy a switch. General 26 w.. 20 yuan

Q: This kind of fluorescent tube is always easy to burn.: The ballast of a fluorescent lamp Where the lights are sold, they sell

Q: How does the energy-saving lamp tube set quota: For example, can be used in dome light, wall lamp, such as the above, set directly absorb dome light, wall lamp, if only is energy-saving lamp tube directly in the lamp on the mouth, can energy saving lamp holder.

Q: Electronic ballast tube lamp change led lamp tube how to change circuit how to do: It is not a direct replacement, it is a light source that is different from each other, and the driver is different. It is necessary to use the (complete replacement). Fluorescent lamp tube + ballast = former fluorescent lamp. LED lamp tube + drive (constant current or stabilized power supply) = new LED lamp. It is not only the size of the wattage, but also the variety of the lamp, which has high voltage, voltage and middle voltage, and the actuator must be used with the lamp. Leds must be aware of the following points when removing the installation: Leds should not be under too much pressure. The installation should be installed by an electrician or the person familiar with the circuit, to avoid the danger of electric shock. Please contact with the purchase manufacturer in time for any distortion or damage

Q: Is a three-male LED fluorescent lamp? How the quality?: An LED fluorescent lamp, depending on what part of a computer is, is like a computer, it's bad from a brand, it's hard to say. Less detailed specification parameters.

Q: Fluorescent fluorescent lamp tube can replace led fluorescent lamp tube?: The original circuit was an alternating current that was attached to the ballast, and the ballast two to the two sides of the fluorescent lamp; To install led fluorescent lights, remove the ballast directly, and the positive and negative poles of the exchange are connected to the two sides of the led fluorescent lamp.

Q: Can a fluorescent tube be used in series?: How much voltage do you need to get through the two 20-watts series, and can a 40-watt ballast provide that high voltage? I don't think so.

Q: How do you know whether a fluorescent tube is good or bad: There is a small filament in each end of the normal daylight lamp, and the two feet on each side of the lamp are interlinked with the multimeter (only very small cold resistance). Working principle is: making after vacuum tubes when filling the silver (mercury), a small drop of water on the walls painted with fluorescent powder, the bulb is started, at the ends of the filament after heating, mercury evaporates into gas, gas is ionized conductive lines into loop, gas release a large number of ultraviolet (uv), at the same time by the ultraviolet radiation fluorescent powder from visible light. In addition, when after the lamp aging on both ends of the filament evaporation guide to black on both ends of the tube, the tube sometimes no broken cannot use the filament lamp to glow (so).
