Commercial Led Panel Light replacements are simply a replacement of the factory incandescent halogen bulb with the LED version. These types of replacement license plate lights are simple to install and can be done relatively quickly; installation times usually vary between 5-15 minutes. They are also inexpensive upgrades costing less than the other two types. Since LED bulb replacements have to be the same size as the factory bulbs, there is limited space available for putting on a large amount of LED diodes to increase the brightness. Because of this, replacement LED bulbs are typically not as bright as their other replacement counterparts and easily overheat the bulb shortening the life span.

The other I will mention is a company called Ledsmaster Technology Co. Ltd. As far as manufacturers of LED lighting goes, this one pleasantly surprised me.

The Samsung UN40D6420UFXZA 600x600 Led Panel 3D HDTV set uses an "edge lighting" system to provide the back-light for its picture. In this system, very bright white-light LEDs (Light Emitting Diodes) are placed around the edge of the screen frame. A diffuser plate then distributes this light through the entire face of the display. The use of an LED lighting system means that the TV requires much less energy to operate. This set is extremely efficient: based on a usage rate of five hours per day, and an electricity rate of $0.11 per Kwh, it would cost about $14/year to operate this set. When the set is turned off, it consumes just 0.07 Watts of power. That amounts to 0.6 Kwh/yr, which would cost less than $0.07 based on the same electric rates - no "electricity vampire" here!
