You gave me negative feedback my not so good friend...
How? Never said anything negative at all
First of all, I don't have a negative opinion - so how could I have left negative feedback?
Secondly, your site is asking me to accept your comment about negative feedback as if it were the answer to my question. And why would you post such a comment and then leave the chat?
I am so sorry if I have mis spoken.
I have had a similar question from a customer that was not very friendly, sorry.
I would be glad to try and help you.
Let me look at your question again
You have a unique operating environment. Let me do a little research on this, I will need to look into the details here.
Please be patient so I can give you the correct answer.
i will get the answer for you asap.
The bulb is Sylvania Quartz # 1500T3Q, 1500 watt, 240V
There are two sockets we use:
First is Leviton, 3000 W, 500 V
Second is Triboro, 3000 W, 250 V
BTW, I am actually a friend of the person you've been dealing with. He is not too good on the computer and not very knowledgeable technically. I have some familiarity with the language you speak, but I am by no means an expert. He asked me to help him solve this problem.
Am researching original information. Two of the ovens had lights when purchased.
Will get you more data soon.
Have contacted the oven manufacturer. Tech support there is sending me two of the original OEM sockets. They actually manufactured the bulbs themselves. The ovens these were originally installed in have been discontinued, and the company no longer is in the business of making deck-style pizza ovens. They have a few of these old sockets, and he is sending me two for me to look at. Expect to receive Tue or Wed and will advise after examing them.
I received one socket from Lang today. It is essentially the same as the ones we've been using.
I've talked to the tech service people at Lang, and they say they think the lamps and sockets on the original equipment were enclosed in some sort of glass tube. But it was so long ago that nobody can even find the part numbers or the original service manuals for those ovens.
Meanwhile, I've been corresponding with a number of specialty lighting manufacturers, and all of them pretty much say the same thing, that temps above 600 - 650 compromise the integrity of the lamp's seal, causing it to leak. Once the halogen escapes, the bulb is gone. That, combined with the corrosive atmosphere, can also crack the ceramic sleeve on the socket. All of the above explains why you can't find a pizza oven with lights in it.
So it looks like there is really no solution to this problem other than to keep replacing the components as they fail, or to find another way of lighting the inside of the oven chamber.
