These are brighter and have a good ratio of lumens to watts. Almost every manufacturer has their own version of a heat sink. The best companies pay the most for high quality lights with only a slight color variation. One of the great difficulties buyers have is the fight against inferior cheap LEDs saturating the market. Only UL Listed products have been tested and can bare the mark of UL. An established company is are far more likely to actually back their warranties and work for repeat business. As stated above these LEDs need some way to dissipate the heat they produce and this is done through a heat sink.

It is becoming increasingly common in the LED industry for companies to claim that their products are UL Compliant.10) Know where the heat goes! This may be one of the most important tips you can read. Since making LEDs is not an exact science, there are great differences in color quality and light intensity. There is a great deal of difference between an LED that is "compliant " and an LED that is listed by UL.9) Do not buy LEDs if your home or office is subject to known frequent voltage spikes. how bright the light is. Lumens represents the amount of light emitted by a light source i.If you are thinking of purchasing an LED par light that does not have an obvious heat sink you are going down one of three paths: 1)The par light is what is called low power and will not produce much light,2) the par is high power but will not last very long(unless the ambient temp is very cold) and 3) the par has a fan built into its Led garden light base.

I have assembled ten tips for buying LEDs to reduce the learning curve. Be careful with high powered LEDs since they can generate a lot of heat which will need to be dissipated. The Kelvin scale is often used to measure the color temperature of light sources. What does this mean? It means that the product has not passed the testing of UL. This in no way means it can pass the stringent tests put forth by UL. Check to see if the company has been around for at least 2 years. It is important to look for this marking on all LED products. Using the scale allows us to quantify, for example the differences between soft white, warm white and cool white. Realize that recommended light levels will vary based on the person and the task. The rest of the LEDs are not discarded but sold to inferior companies at much lower rates.3) Check the CRI. When purchasing light bulbs, however, don't assume that more watts means more light, more lumens means more light. The fans in the par bulbs are the same as those used in IBM laptop computers and are rated for 70,000 hours. Excessive heat buildup is the leading cause of failure in all high powered LED lights.

The internet is full of new companies that have purchased very cheap, low grade LEDs. When a LED is created it is first inspected for color and light quality and sorted("binned") into different categories. Because of this, heat sinks can vary greatly with some being so elaborate and large that it is obvious that they cannot be sold separately but must come as part of a unit. The color temperature of an incandescent light bulb is about 3000k. This is especially true with regards to color variation, which most companies do not considered a defect. Know your lights.8) Check for lumen output. CFLs start out with about 60 lumens per watt but average about 50 lumens per watt just to give you an idea. The further the light is from what you wished illuminated the higher wattage power you will want.With most businesses that sell new technology, a good portion of an employees' time is spent in teaching about the product.The low power LED light is made up of many very small LEDs, usually 5 millimeter.

You may be unaware of voltage spikes and they may occur in seemingly random areas of your home or office. High powered energy efficient LEDs have a single LED chip usually from 1-5 watts. This is not considered a manufacturers defect and is never covered by any warranty. This is normally construed as warm white.e.. These do not produce a great amount
