Hi All,
Not a new member here, but this is my first post! I am an exhibition coordinator for the School of Visual Arts, where we install and remove 50 exhibitions, both student and professional, across 3 locations each year. At one of our locations we have an Edison Price lighting system which we have been having some issues with.
I was wondering if anyone else has experience with Edison Price's Artima 38 0 fixtures (here is a link: http://www.epl.com/guide_page.cfm?id=AE49DC58B1A7150A4F5B889633A85146 )
We have been having 2 major issues and a host of minor issues with these fixtures. I am going to try to describe the operation of these fixtures, forgive my description, it is not easy to put into words. I will try to post some illustrative pictures when I can, but we don't use them at this location so I don't have any handy right now.
#1 is that after repeated uses the tension clips that hold the fixtures into the tracks have been wearing out after repeated use (these fixtures are about 2 years old). If you are not familiar with the way these work, to install or remove the fixture from the track you manually squeeze these two clips, which pulls a small tab out of the track which releases the fixture.You then pull (or push) the track adapter out of the track. There are two clips on each end of the track adapter, on one end the clip surrounds the contacts for the track, on the other there is nothing between them. The side without the contacts is where we are seeing problems, since there is nothing in-between either side of the tension clips to keep them spread apart, after repeated uses they lose their memory and become pinched together. We've tried bending them back, but once they've been squeezed together they don't hold their shape anymore, allowing for the possibility for the fixture to actually fall out of the track (which has happened once while my predecessor was performing an install).
#2 is that the attachment between the yoke and the light shield (allowing for vertical rotation of the lamp) has been failing. The yoke attaches to a knuckle and there is a small hex screw that keeps the yoke on the knuckle through tension. The hex screw can be loosened to allow for rotation of the lamp. The problem we have is that on some of the fixtures the yoke slips off the knuckle no matter how much the hex screw is tightened. If there was a lip of a groove in the knuckle this wouldn't be a problem but since the knuckle is just a straight aluminum post the yoke can slip off of the knuckle. This isn't a big safety issue as the light shield is riveted on the other side, but obviously not how the fixtures are meant to function.
I came into this situation after these fixtures had been installed for a year and already had these problems. I don't know the exact circumstances under which they first started to appear, but I've been having problems with them from day 1. I am currently in discussion with our local rep for E.P. and he is saying that these are not problems he has heard about from any of his other clients. It could simply be that our situation exposes these fixtures to a higher amount of "abuse" (although I hate to use that word since I always do my best to handle them carefully) than normal.
Has anyone else experienced any of these issues?
