        <description><![CDATA[There's no way that this bulb will last that long in real life applications.  Perhaps it will make it 4-5 years tops.  Modern circuit boards and components have relatively short lifespans of a couple of years.  20?  Not a chance.]]></description>

        <description><![CDATA[Why this lamp is lightning almost 360 space ?Most uses of light need half space or less. To be clear, street lightning need to light the street, not the sky. So ? cut power by 50% and orient the lamp correctly.Another example is the Fresnel light house where the lens system attempts to collect and re-direct light that goes away in the wrong direction.This lamp can be manufactured so that the light goes only where it is needed.]]></description>

        <description><![CDATA[Work is still done when the user lifts up the 10-15 Kg bag of sand. That has to be counted. It is basically 'free', but from an engineering standpoint, it is some 20-30 &quot;meter-Kg-seconds&quot; of input power, and I assure you the mechanical generator in the Gravity Light is nowhere as efficient (30-50%?) as the plug-in-wall converter (80-95%). It is the world's most efficient, if the only consideration is 'zero utility electricity' consumption. It's like the old cuckoo clock. has to be wound. It's still a great and very-needed product and I hope it succeeds.]]></description>

        <description><![CDATA[LED efficiency increases as the current is reduced, but that value is different for each type of die made. It makes some sense to have a slab of one thousand 20mA LEDs over ten 2-Ampere ones. Still, LED and fluorescent are similarly efficient. Until the cost of LED comes down, fluorescent is the best choice for the frugal light-user. CFLs are not that efficient, but the long tubes are, and the companies who make that tech. continually strive to improve both lamp and ballast due to the &quot;LED threat&quot;. Haha it's the good old fashioned design of the fluorescent lamp that is best cost/lumen today, but architects and designers don't like to be limited to a certain shape. I hope this project will progress and improve the choices and costs for efficient lighting.]]></description>

        <description><![CDATA[The claim &quot;worlds most energy efficient lightbulb&quot; may noy be that true. Look at another Kickstart project, the &quot;Gravity Light&quot;. One time cost of $10 and gravity produces the power. Zero cost involved after the initial purchase. That is more likely the &quot;worlds most energy efficient lightbulb&quot;.]]></description>

        <description><![CDATA[Yes this is a good design and probably would have taken the market by storm 5 to 10 years ago!  The brightness appears to be excellent however the high cost is the major deterrentNow with the development of the much more efficient plastic luminescent plastic seem set to take the market.  The low predictive cost will make it more acceptable.]]></description>
