Addendum 7/23/14: Meanwhile, 25% of the lamps supplied broken. I initially thought that possibly it is that when a downward lamp cooling is poor, even light bulbs are now affected, where the outlet opening is at the top, so that a good cooling should be present.
Attempts to achieve conversion.
Addendum 1/24/15:
Have complained at the time and get sent to establishing appropriate pressure of 10 new lamps. Since has gone no more broken. After the bulbs have slightly different colors of light, I suspect that I have received a bad batch or have been design changes it. If again what is broken, I'll get back.
