Product Description:

 bulb is a creative product comparing with common LED bulbs. By adopting artistical design idea, SFT applies magnolia shape into the LED bulb and creates the patented distributing cavity technology. With this technology, the omnidirectional lighting and better thermal dissipation can be realized. The lamp offers naturally warm light with beautiful sparking effect, while consuming 5W energy only, which meets the Energy Star standard.

* Crystal sparking warm light by clear bulb, comfortable soft warm light by frosted bulb. Perfect for chandelier 
   application.

* 300° light distribution. All around illumination.
* Group dimming with 30-40 lamps depending on dimmer capability.
* Small size with high lumen output.
* Cree inside: Excellent stability of light color temperature by CREE® white LED technology.
* Long life, 25000 hr guarantees no maintenance over 22.8 years if lit 3 hrs a day.
* Energy saving: up to 80% energy saving.
* True vision by high color rendering index.
* No mercury, no UV light, no hazardous material, benefit for your health and environmental friendly

Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
5, the three have different service life. The service life of incandescent lamp is in 1000 hours or so, the service life of energy-saving lamp is in 6000-8000 hours, and the service life of LED lamp can reach more than 30 thousand hours.
Q:How to identify Ic constant current LED bulb?
Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.
Q:What's the cause of the noise during the aging of LED bulb bulbs?
The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.
Q:How to choose the bulb power?
If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.
Q:What are the driving IC used in LED bulb?
Here are some of the models you want to know. You can contact me by mail and provide your detailed information and samples:Isolation without PFFT833S11 2.5W FT833A11 3-5WFT833B12 7-9W FT825 series 7-60WIsolation belt PFFT8900, 30W, FT8901 series adjustable light 30WFT8901B 7W, FT8901/2DD, DIP, built-in MOS, 24W adjustable lightNon isolation without PF:FT886A 7-24W FT883A 3-5W
Q:Will the power of the LED bulb grow longer and longer? Why?
Voltage problems, as well as unstable factors.Long time no change, should
Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
The difference of power factor is large, and the resistance capacitance pressure drop is below 0.5 PF. Constant current and constant voltage drive PF over 0.9. The resistance drop pressure is really attractive, after all, the price is there. The average person doesn't understand the look.
Q:Is it possible to manually weld LED bulb bulbs?
You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
Q:What is the 15 Watt lumen of the LED bulb?
Each brand has different bulb qualities, probably around 1W between 60-85LM/W.
Q:LED how to classify bulb bulbs?See some LED bubble bulb specifications are written in A60, A45, and some are written G60, G45, I do not know, in addition to the maximum diameter of the same, what is the difference between the meaning of A and G?In addition, how can the whole LED bulb be classified, only by the maximum diameter, or with other classifications?,
No other special significanceThe type of label has made their size, type or number of series LED lamp series models more balls of small power spherical. No number certain special shape at present. High power may be more common. Watts arrangement model
