Ordered Monday and Wednesday already in hand, I have a pear installed the same. The luminosity pleasantly surprised me. Almost as bright as ne 100w bulb. What exactly is the power consumption and heat generation is I can not say to an hour ago. However, you can still turn out without burning the bulb after this hour operation itself. Although very warm but not really hot. The extent to which the long term behaves and what the longevity of the bulb is to be seen. Nothing siehts well. Updates to follow with the time when it should change anything.
