Q:What material is LED fluorescent lamp fittings, such as shell, block?

Shell is commonly aluminum and plastic, aluminium is made LED lamp cooling body aluminum profile, molding is a PC or PMMA material, high transparency requirement light effect is good, ACTS as a chimney - the light part of the leds. Plug, there are all kinds of resin, plastic (white PC/PP), metal stamping (aluminum), the role of is sealed on both ends of the tubes, at the same time support the light foot.

Q:What's the difference between a single input and a double-end input?

Like our products, single side used on special occasions, be flat installation place, double side is directly used in the traditional ordinary lamp, so change the LED fluorescent lamp is very convenient.

Q:The difference between LED and fluorescent lamps

LED is a solid-state light source that has a long life and is environmentally friendly and efficient, and leds are now safer.

Q:How to detect the good and bad of the fluorescent lamp

If you measure the resistance at both ends, it's not bad

Q:What does LED light tube integration mean

Integration is a strap that can be plugged into a power supply. The other kind of branch is that only the lamp tube needs to be matched with the stent, the old stents in the home also can be used, this is for the people to replace and transform also save the cost

Q:Which is better? In terms of power and price

I think this brother is not very clear about leds; In fact, the lamp contains the way of the patch Led lamp bead classification 1. Straight insert small power specifications are as follows: straw hat/helmet, round head, concave, ellipse, tombstone type (2 * 3 * 4) bullet, flat head, type (3/5 / flat bread) piranha, etc. 2. SMD patches are usually divided into (3020/3528/5050, these are positive luminescence) / 1016/1024, and these are the lateral luminescent sources. 3. Large power leds are not classified into the patch series, their power and current usage are different, and the photoelectric parameters are very different. Single single high power LED light source, such as no heat dissipation base (generally for hexagonal aluminum), its appearance and the average patch without too big gap, high power LED light source is circular, encapsulation mode basic and SMD patch is the same, but with SMD patch in the conditions of use/environment/effect has essential difference. Photosynthetic efficiency as to what you say, he is equal to the luminous flux/power is the power points, as we have 3014 (0.1 W), 3528 (0.06 W), 2835 (0.5 W)... The flux is also the customer's requirement, we have 5 to 60 lm here, of course the price is different. Hope is useful to you

Q:How do I get the four joints of the LED fluorescent tube, and I'm going to do any two of them that can search through the AC220V to light up, and not make the wire and the zero line together? thank you

I can't put a picture on it, you can try it yourself, add a rectification bridge at each end of the tube, and then you put the positive plus positive on both sides, negative plus negative, onto the next bridge

Q:The light tube is directly connected to the zero fire line at 220V, and the other end is empty

You are good for nothing! It's nice to be complimented on the quality of your air switch.

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! If the screw lamp, generally in the luminous flux of 50-60 lm/W, and haven't consider it droop, even if Edison lamp just pack up and give a person feel very bright, but as long as a long time can tell what separates! Hope can bring convenience to a friend's life and work!

Q:Brightness, longevity The current led lighting tube is 90-100lm/watt, and the life span is more than 20,000 hours, and the chips and power supply should be paid attention to. We adopt a 3-ampere, long power supply to ensure the quality of the lamp.

You are not professional can not calculate, because of the brightness of the LED is unknown, the 1 w LED brightness lm from 10 to 110 lm, can achieve the best LED 1 w = 130 lm, but on the market generally between 60-90 lm, which is 15 wled only 30 to 45 w energy-saving daylight lamp brightness, only 180 w to 270 w old incandescent lamp brightness. The best one we produce is 15W = 60W daylight saving tube. This one depends on the light, and you can see it visually.
