I have been thinking about this for a long time. I am glad
somebody have made it.   60% energy saving (even more) is
possible.  Actually the IR coating can improve the color
balance of the light.   Can anybody tell me if this is already
a product on the market or where I can find more information.
Thanks in advance.
