1. Probably early 1990's.
2. If you are talking about an
ellipsoidal spot
fixture, look on the
fixture yoke and it will usually have this information.
If you are talking about a
Followspot, it may be on the rear nameplate.
Or Google the
fixture and find the owner's
manual or instruction sheet. Or post a photo and we can figure it out.
Normally I would say look at the lamp that's in it, but too many folks put any lamp that fits the
socket (usually NOT the correct one).
If your school is a public entity, they probably have a lamp contract (think hallway and classroom lighting) with a big lighting distributor. Have your teacher or principal talk
to your school district Maintenance head (not the school custodian) or chief Media Center person to ask where they are getting their lamps.
Otherwise, you can order from places like Lampline.com.
3. The
Colortran ENR dimmers generally default to
Colortran's control
protocol CMX. The
ETC Element outputs
DMX. They are not the same exactly.
The
Colortran ENR
Dimmer Racks are capable of receiving either
CMX or
DMX. The key is to hit the ENR's reset
button after the
DMX has been applied to the ENR
Dimmer Rack.
This will cause the
system to use
DMX input. If the
DMX source is on before the rack powers up, it will
switch to
DMX as well.
If you turn the
DMX console OFF
and the rack loses
power, it will reset to
CMX.
Normally, folks never turn their
dimmer racks off, so if the
Element and ENR are working together OK now, everything should be fine.
4. It is standard practice to run
LED fixtures from
non-dim (constant)
power, NOT
thru dimmed
power even with the
dimmer at full.
the CS PARs are nice fixtures..... take care of them.
