Derek long time buddy, nice to hear from you.
Really
emery Cloth the same as Chrocus Cloth? Similar but McMaster
https://www.mcmaster.com/products/emery-cloth/?SrchEntryWebPart_InpBox=emery+cloth Not the same. I
stock both types and neither are similar. Silicone abrasive fiber from grinder to Dremmel wheels I more use these days, but none jermain to a G-9.5 based
HPL lamp. That's nutz above about a
nail is it? 25 years ago one might have been able to re-surface say a
PAR 64 lamp pad at best, but mostly it's resurfacing G-22 and larger, and Medium
pre-focus or screw based and larger lamp sockets.
Really dislike the S-4 JR
fixture... lamp explodes or expands in dia. due to finger touch ballooning, you have to take apart the
fixture to remove it. Never put more than a 575w lamp into it.
Agree with most above, bad lamp
socket are cheap to replace, and as a rule, do not ever put a bad lamp with corroded pins into a perfectly good lamp
socket. Especially in this pin size range or lower in size. Believe I started that standard of disease concept to which I'm glad has carried on.
The 115v verses 120v, verses extended life
HPL lamp all depends on the venu's individual needs. Artistically if all lights of a certain lamp are the same, one adjusts the eye to it and you have head room for specials to be brighter with a lot of options. How did they ever light stages with less efficient fixtures?
Jody, seemingly you are either student or School maintinence person charged with or maintaining the lights. I know it gets hard in caring.. keep it up, we are with you and the teacher is in the same world also in getting stuff done. Clarify please the status in defining what you can do. Student or school staff? The teacher seemingly has some training and these problems might be pre-this person. A professional or lighting company as offered as advice in the past is possibly the best above advice that can be offered. Locally from company, college
etc. what to do should be free. Take bids in getting many to offer local advice in what's needed.
Not just "oh' you need an upgrade", but servicing the fixtures or with the upgrade to
LED what else is needed in either case. And or the... "oh' we can replace all these lights with a few
LED PAR's".... Large choices in any way professionally serviced in how to properly professionally deal with the situation.... There are modern theories in lighting where various
LED lights will replace what is there. I certainly have installed a lot of them over the past couple of years. Others where the S-4
LED lamp cap will replace. Others from a High Scool local to me in asking for help, perhaps just a service
call for now will get them
thru the season. There is options for your school needs.
Of news on the good side! A few months ago I worked on a S-4
incandescent conversion to the
LED caps for
Leko's. Inspected and cleaned the interiors of the body/
gate of the fixtures in doing so. Sent the assembled
lens train
thru the school's dish washer
system for the cafitera. This without taking apart the
lens train assemblies!
Worked amazingly in cleaning the
lens train assemblies - highly recommended in the first time doing so for industrial dish washer cleaning of lenses, this much less entire
lens train assemblies. (Might have to inspect the screws soon after, or add oil to them given aluminum/black oxide and moisture... tba thing.)
