Done for now. (some of it has been posted before.)
Much of what I see is under negotiation and not public knowledge out of say "your plugs suck," what are you going to do about it - take these
dimmer racks back and give us a loaner while you re-do them, or
send a tech person out to fix them? The connectors have issues, this new rubber used in the Socapex-compatible
panel mount connector to retain the sockets is a wee
bit more soft than used to be used. It's allowing pins to pushed in which if they than don't engage a
plug sufficiently will have a wee
bit of resistance. Resistance is heat, heat means that if solder type instead of
crimp connection of
wire to pin means we now could have melted solder that than means liquid electricity in shorting between hot/
neutral and worse yet, between phases.
Or, here is a hundred lamps of this type with pinch cracks in the
pinch seal. Is this a problem that should be corrected? This much less on some of the lamps style, pinch bubbles around the electrodes that as they approach the pinch crack could leak and explode in an expensive way. More of a concern to solve design-wise? Something to be concerned about? What's this about warranty also covering the lighting
fixture installed in, say to replace the
reflector and other components that lamp in exploding took out?
Ok, basic electricity says the "skin
effect" (Question of the day - another one, what is the skin
effect.) On these very high wattage (and expensive) xenon lamps, some out of the factory have a sort of
wire rope that is tightly twisted leading to the
envelope pinch of the lamp. Others at random have one side that has somewhat un-twisted, others have up to both sides so seriously un-twisted that they sort of
mushroom out of the lamp
base. Given the skin
effect of
wire, can this un-twisting of the lead in
wire play a
role in lamp failure?
But I digress... yep, wall of shame with lots of stuff, a whole 'nother wall of shame ready to go once I get about building it. On a day to day basis, it's more like stuff like gee, some manufacturer attached a 1Kw
Mogul Screwbase metal halide lamp directly to a fan guard for their lighting
fixture. Seems that a fan guard is not really rated for mounting a heavy lamp vertically off it and one fan guard broke. Lamp then melted into the side of the plastic
fixture once the
power cord was all holding it in place. This much less pulse rated 1Kw lamp, no grounding and no isolation between fan grill and lamp
base terminals. Lots of issues abound by way of how this company did it - even ran the fans backwards in keeping them cool. Fan quits, lamp over heats and its supports fan, lamp
base and lamp now melt through the plastic mountings for them. We now have the
fixture wiring cords holding up these things that otherwise
drop on those below or explode in already having melted through the 200F plastic guard for them. Long story, some production company is in negotiation with where I work to correct all these and other issues for them. Fascinating stuff constantly.
