1. What are the benefits of LED lights over traditional MH/HPS lights?
* Lower energy consumption; Up to 80 percent of electrical energy is converted to light energy; For this reason, lower-wattage LED lights may replace comparable light fixtures. For example, a 100W LED shoebox light may replace a 300W metal halide shoebox light.
●Longer service life; LED bulbs can last up to 100,000 hours
●Durability; LED bulbs are resistant to thermal, vibrating shocks and turn on instantly from -40°C to 185°C, making them ideal for applications subject to frequent on-off cycling
●Flexibility; LEDs allow for directional distribution of light
●No infrared or ultraviolet radiation – UV light attracts bugs
●No toxic chemicals; LEDs contain no mercury and do not require ballasts, which are often manufactured with PCBs
●Very low heat generation; LEDs are can reduce climate control costs and are especially suited for cold storage facilities
●No frequency interference; no ballast to interfere with radio and television signals
●Wide range of color; LEDs can be manufactured to produce all colors of the spectrum without filters as well as white light in a variety of color temperatures.
2. Do you have LM 79 and LM 80 reports for your lights?
CROWNDALED has LM 79 data for most of the high wattage lights that it offers. All of these reports are independently verified at the labs of independent testing company. All of the LEDs that we use have extensive LM 80 data that is verified independently. We furnish this data to all of our customers.
3. What is the most common reason LEDs fail?
Heat. Heat is the enemy of electronics, the hotter it is, the shorter lifespan the light. However, with good design, you can
create a light or fixture that can withstand some high heat environments. Typically a fixture or bulb with an external driver will last longer than an integrated fixture that has the LEDs and driver as one unit.
4. What component of the LED system is typically the first to fail?
Almost always, it is the driver. That is why it is important to know who makes the driver in the LED fixture or retrofit kits you
purchase. Typically a good driver should last more than 50,000 hours.
5. What is L70?
L70 is the amount of time it takes for a light to degrade to 70% of initial lumen output.
6. What is important in regards to color consistency?
To make the color more consistent, we use the exact same bin for all the lights in a single project. CROWNDALED will finer tune the binning that the LED manufacturer has performed. We have strong relationship with CREE/OSRAM/Philips and other LED chip suppliers, and can fine-tune the final color output. In most instances, we have guaranteed a color matching of less than 25 degrees Kelvin.
7. What are the advantages of dimming LEDs?
* Saves energy, because less energy is used for reduced output levels.
●Extends life; the electronic components run cooler.
●Increases flexibility in usage of space. A brightly lit space for reading or an office space can turn into a
presentation/conference area by dimming.
●Increases productivity by enabling individual control of lights in order to reduce eye strain and fatigue, or to improve
8. How many lumens do I need to replace 400W Metal Halide High Bay?
The typical range is as low as 17,000 lumens and as high as 23,000 lumens. Specific Photo-metrics plays a major part in
determining how much you need, spacing, and reflectivity of the environment. In general, 150W LED Linear highbay or UFO highbay can replace 400W Metal Halide High Bay.
9. How to get the samples?
We will ship the samples to you by DHL, UPS, FEDEX, OR EMS after you confirmed what you need. Door to door service! You will get your lights at your home.
10. Are samples available for test?
