  • >> 1)What are the lens degree options?

    A: We have three conventional lens for your options, saying 15°,30°and 45°.If you have specific requirement on degree, we can also custom for you.

  • >> 2)What are the advantages of LED lights?
    A:LED lights bring several advantages such as energy efficiency, durability,long lifespan, no UV emissions, no flicker and dramatically reduced maintenance requirements.
     
  • >> 3)Are LEDs affected by extreme conditions?
    A:LEDs are geared for harsh environments. LEDs function from -40F to 180F. There is no delay or required "warm up time" for LEDs to function
  • >> 4)Warm White or Cool White?
    A:Warm white are predominately used in places like lounges, bedrooms, dinning areas etc where the Cool White is used in more work related areas such as kitchens, bathrooms, outside eve areas and garages. Cool whites are associated with concentration and help to reduce visual and mental fatigue. In general cool white appears brighter than warm white. The warm white and cool white descriptions are only a guide to colour within a certain range, different bulbs or different batches of the same bulb may vary in colour within that range.
  • >> 5)LED Chips?
    A:Our conventional products use Edison (Taiwan)chips,also Cree (USA)chips is available too.
  • >> 6)What’s High Power LEDs?
    A:High power LEDs come in 1-3 watt packages. They are driven at much higher current, typically 350, 700, or 1000 mA, and—with current technology—can produce 40-80 lumens per 1-watt package.
  • >> 7)How long does the life expectancy of LED bulbs?
    A: Normally it is 50,000 hrs.There are 8,760 hours in a year, so here's what 50,000 hours works out to
    be, depending on lamp hours of operation.
    24 hours a day 5.7 years
    18 hours per day 7.6 years
    12 hours per day 11.4 years
    8 hours per day 17.1 years
  • >> 8)What can affect the LED junction temperature?
    A:There are three things which can affect the junction temperature of LED’s:drive current, thermal path and ambient temperature. In general, the higherthe drive current, the greater the heat generated at the junction. Heat must be moved away from the junction in order to maintain expected light output, lifespan and color. The amount of heat that can be removed depends uponthe ambient temperature and the design of the thermal path from thejunction to the surroundings. Typically the junction temperature should be maintained below 120°C.
  • >> 9)What’s DMX 512?
    DMX 512 agreement is the abbreviation of Digital Multipiex, light industry of Digital equipment general signal control protocol,also is a kind of international agreements.

  • >> 1) Any discount for the fixtures?How about the warranty?

    A:
    1、Normally our quotation is based on MOQ price. Of course, we can offer a more competitive batch price based on large QTY.
    2、We offer one-year warranty. We promise to repair defective fixtures (not for human causes) free of charge within warranty period. What’s more, we can offer pay-needed maintenance service when fixtures are beyond warranty.

  • >> 2)Is there any certification of the lights?

    A: Our products of all series pass CE certification, and some of them pass UL certification.

  • >> 3)Why prices you provide are higher than other suppliers?
    A:
    1、Frankly speaking, prices we offer are surely not the lowest in market as we won’t cut down cost by lower quality. We only purchase credible raw materials: LED bulbs we use are made by EDISON, IC by GUOBAN, and power supplies pass CE or UL certification. Furthermore, most  of our products are sold oversea, so it is vital for us to provide better service and product quality.
