For testing our lights we came up with our own system.

The reason we came up with our own system was give our customers a better idea of what to expect from our lights. We also did this because there had been a lot of inaccurate reporting in the industry. This inaccurate reporting mostly involves the cluster bulb. If a cluster bulb has 20 LEDs on it and each LED emits 5 lumen then the lumen out-put is being reported as 100 lumen. Being that some of the LEDs are on the back side of that light, you are not getting all the light that those LEDs are emitting. Most assuredly you are getting some light from those LEDs as they are facing a white concave back ground but that light is not putting out a 100 lumen.

How we came up with our testing environment was, we built a cabinet where we could block out the light from other sources. Then we got a meter which is designed to measure light. The inside of the cabinet is black so to not reflect light then we installed an adjustable shelf so that we could calibrate our system. To calibrate, we bought several 110 volt light bulbs from some large lighting companies that had lumen out-put listed on the packaging. We then moved the shelf until the meter matched what the 110 volt light bulb manufacturer said was the lumen out-put.

When it comes to testing our lights we test under every condition that a customer might use the particular LED replacement light. Below is a light holder/lamp with a clear lens and a white lens that is attached to an ajustable shelf. The light holder/lamp in your unit may be different and could get different results but you will get a good idea how bright a particular LED replacement will be compared to the light you have.
