How many LEDs does it take to replace an HPS, incandescent or florescent light
This can vary for each specific application, directionality and the physical area that requires illumination can play a big role in determining this. As a basic guide, a 6 LED light fixture provides approximately as much light as a standard 60W incandescent light bulb, and a 24 LED light fixture is equivalent to a 150W HPS lamp.
How many lights should I put in? What is a lumen? And how bright is the light?
As a rule of thumb and in approximation: One LED is equal to a 10-watt incandescent bulb in brightness. One LED light is approximately equal to a 60 watt incandescent because it has 6 LEDs in it. A lumen is a unit of measurement for light and a standard 60 watt incandescent is 900 lumens of omni directional light and 6 LEDs offer over 600 lumens of directional light.
What happens when a bulb burns out?
Typically LEDs do not 'burn out' like standard light bulbs. Rather, they gradually degrade over time. Our fixtures should retain 70% or more of their brightness for 50,000 hours, possibly for up to 100,000 hours, which is 20 years if operated for 12 hours a day.
What is the difference between a floodlight and spotlight
LED spotlights: output a narrower beam of light, typically less than 30 degrees wide. Most of the light from a spotlight is concentrated onto a relatively small area producing a bright spot.
LED floodlights: output a wider beam of light, up to 160 degrees, so the light from a LED floodlight is spread out over a much larger area. The light is more concentrated, thus a spotlight will appear brighter than a floodlight but only within its narrower beam. An LED spotlight is more suited to illuminating objects and LED floodlight is more suited to illuminating areas.
What is the difference between Cool White and Warm White?
Warm White was developed to mimic an incandescent light bulb and may be a better choice for applications that require a softer light in some display or residential uses.
Cool White is more like the colour of white that is produced by fluorescent lights. It is 25% brighter than Warm White and is better for applications that require increased illumination or more energy efficient projects.
Which colour to use where comes down to an individual's personal preference.
Are bulbs with more LEDs brighter than bulbs with less?
The number of LEDs is not the determining factor of an LED bulb or the brightness of an LED globe. Different types of LEDs vary greatly in brightness. The wattage of a LED bulb is a better indicator of the light output. The typical light output for the current generation of white
LEDs is about 30 lumens per watt.
However, the newest power LEDS from cree are in a different category with output up to 65 lumens per watt. Just three of these big LEDs can output as much light as 100 or more common LEDs.
How bright are LED light bulbs?
LED bulbs or LED globes available for standard fixtures vary in brightness from less than 50 lumens up to about 400 lumens. The brightest LED bulbs for standard fixtures are the floodlights and spotlights. The brightest of these uses about 11 watts and produces light comparable to a 50-watt incandescent. The non-directional LED bulbs are best for lighting small areas, low level safety lighting, night-lights, mood lighting, or decorative accent lighting.
Using non-directional LEDs to replace incandescents for general room lighting is not really practical at this time. Our brightest nondirectional LED bulb (96 LEDs) uses 10 watts to produce light comparable to a 40-watt incandescent.
How efficient are LED bulbs compared to incandescent bulbs?
Most LED light bulbs or LED globes are five to six times as efficient as incandescent bulbs. In other words, they use only 10% to 20% as much electricity to produce the same amount of light. The newest generations of LED's are eight to ten times as efficient as incandescent bulbs. We use these new LEDs in our 5W LED bulbs, 6W LED bulbs and 9W LED bulbs.
