We have 12 Stand 6"fresnels in our inventory. Age - 10 yrs old, same
as the rest of our inventory. This past year I am going through GE
BTR lamps in these like crazy. I use one specific brand from our
supplier and never had any problems with them until 2 yrs ago when we
relamped. They all seem to blow when doing a lamp check when first
firing up he board. They always fail with two black marks on he side
of the glass in the middle and the filaments are rolling around in the
glass. No finger prints on the glass. mainly cuz I use editors
gloves to change them.=20
I have taken to setting the patch for these dimmers to be 95% at full
on the channel but just blew another one the other day. I have also
set the focus slightly in from full flood on all fixtures so they lamp
is back from a lens a bit. Still it blows. =20
Other thing I note these lamps are getting very hard to get in and out
of the sockets. Hard even when they were new. The difference in the
size of the two flanges is difficult to see when in the dark catwalk.
My maglight helps but I don't have 3 hands. <grin>
Anyone else experiencing difficulties with this.??
cheers
