You don’t really need an inverter for most computers, laptops any way. They already run on DC but have their own inverters to run on the system. A log of energy is lost going through the inverter so we should emphasize having more things that run on DC which after all is the future.

One thing about these light bulbs: although LED’s are inherently more efficient than Incandescent or CFL light bulbs, they do require cooling, and heat sinking to maintain their efficiency, output, and longevity. This means that any bulbs you do buy, should not be used in insulated “can” style light fixtures. The reason is this: 1) heat rises, 2) any heat given off by the bulb will be trapped in the fixture, and 3) any excess heat over even short periods of time will damage the LED’s, and destroy them. These LED bulbs are much better suited to free standing light fixtures, in areas with lots of moving air.
Also, if LED efficiency is what you are looking for, then do not purchase any LED bulb as shown above (the work light with several score 5mm LED’s). Purchase bulbs that use a reputable, and much more efficient “high power” LED from companies such as Cree, LumiLED’s, Seoul Semmiconductors, etc., as these LED’s (when designed for their proper applications) are many times more efficient, and will not fade as quickly (10′s of thousands of hours as opposed to a few dozen, for 5mm LED’s), and their color accuracy will be much higher.
