FAQ:

Q1: What is the Warranty for SucoGreen lamps?

A1:  For the lamps,we have 3 years warranty.If any quality problems on our side occured in this period ,we will take on the shipping cost and replacement.

 

Q2:  What is colour temperature?

A2: BRTECH Lighting offer lamps in warm, natural, pure and cool  white with colour temperatures measured in  Kelvin (K)The lower the colour temperature is, the warmer  the light given by the LED:

2700K-3200K = Warm white 

4000K-4500K = Natural white 

5000K-5500K = Pure white 

6000K-6500K = Cool white 

 

Q3:: What is CRI?

A3: CRI is a figure which feedback the real objects colors.Higher CRI with higher cost.For LED tubes,the CRI is mostly 70-75Ra,and 80Ra with higher cost.But there are some suppliers write a high data to attract clients,please note.

 

Q4: Will your LED light bulbs work on a dimmer switch?

A4: We do not recommend using our LED light bulbs on a dimmer switch, this type of switch can potentially cause damage to the bulb.

 

Q5: What is the specific size of the screw base on your Edison base LED bulbs?

A5: The size is E-27/E-26. This size works in all common fixtures.

 

Q6: Why does my LED light bulb not work properly in extreme temperatures?

A6: Any temperature below 14 F or above 122 F may cause a LED bulb to flicker, dim, change color, or cease to functionOnce the LED bulb is returned to an operational environment it should began to work properly.

 

Q7: What is the AC Voltage tolerance for our LED bulbs?

A7: Their AC voltage tolerance is +/- 10%.

 

Q8: Do your LED bulbs emit UV light?

A8: No. But you should never point an LED light into your eyes. The light is very bright and could cause damage.

 

Q9:Is there cheap shipping cost to import to our country?

A9: For small order,express will be best.And for bulk order,sea ship way is best but take much time.

For urgent orders,we suggest via air to airport plus our ship partner send to your door.

 

Q10:Can we get support if we have our own market position?

A10: Please inform us your detailed mind on your market demand,we will discuss and propose helpful suggestion for you,to find the best solution for you.

Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
Q:LED what are the bulb screws?
LED bulb adopts the existing method of incandescent lamp interface, the general screw is E27E14E40 (three). E for screw holes, figures for size, diameter, size. The most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.
Q:What's the reason for the LED bulb strobe?
8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.
Q:What is the AC voltage of the LED bulb?
LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. With all the advantages of LED lamps: 1, energy saving, environmental protection; 2, long service life; 3, no stroboscopic, green.More energy-saving: LED lamp energy consumption is energy-saving lamp 1/4, incandescent lamp 1/10Long life: LED lamp life of up to 50 thousand hours, life expectancy is 3-5 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no mercury vapor, harmful substances can be recycled to protect the green earth.Full color change: rich colors, vivid and delicate patterns and effects can be displayed.Installation convenience: simple installation, can replace incandescent lamp directly, maintenance cost is extremely low.
Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!
Sandblasting can be transparent, light is not dazzling,But will still see the light...
Q:How to choose the bulb power?
The basic types of bulb power are divided into two types: isolated and non isolated
Q:LED bulb PC, will the white cover affect the color temperature of the finished lamp?
Our company is doing LED lamps, about the color temperature has indeed been deviation, we call this phenomenon called drift. But there will be no 6000K drift, and there are two possibilities for you
Q:What advantages does LED bulb replace energy saving lamp?
More importantly, 3W's LED light can replace 15W's energy saving light
Q:What's the difference between a glass cap for a bulb and a PC hood?
1, impact strength comparisonPC and glass is the biggest difference resistance shock, PC is transparent plastic, the most resistant to impact, smashing not broken.Similarly, PC is 200-300 times the impact resistance of glass. PC is 30-50 times the impact strength of PMMA acrylic.
Q:LED bulb w can replace 40W incandescent lamp
The light efficiency LED lamp better can reach more than 150lm, Hailin's general light efficiency is more than 100 in general can be done, so 3w-5w is almost completely can replace 40W incandescent lamp. Mainly depends on the quality and LED lamp lamp light etc.. The LED Lantern Festival will gradually replace incandescent and fluorescent lights, so more understanding is right. Early use, early save money. I hope there is help for your O (a _ U) O
