Replacement bulbs for Zone VI 5x7 Type II VC enlarger

[Nacio Jan Broown]

Does anyone know a source for replacement bulbs? Or some alternative? My bulbs are still ok but I'm looking toward the future when they fail.

Look up Heiland LED, and bring money!

Do a search for Aristo Cold Light and bring less money

Pull a bulb out of the head, and look at the 3 letter code on it... Then search on-line...

Look for NOS USA or Japan bulbs...

Question being, how does one install them?

I have a green spare for my 5x7, and both for my 8x10 head. I purchased these after the blue 5x7 became no longer available, but while they still had spares for 8x10. Of course, I need to keep what I have.

Fortunately, neither the 8x10, nor the 5x7 heads get much use. I use my Zone VI enlarger, which I really like, for 4x5 with a Beseler 45S customized head.

I believe the company that bought out Aristo sells replacement fluorescent bulbs. If not I'd contact Richard Ritter and ask him if he has any suggestions. They're not cheap but they were available .

[RichardRitter]

The bulbs will last longer then the drivers that power the bulbs. the drivers were custom made and are no longer available.

When the bulbs die, you should get about 10000 hours of use I would put in LEDs.

There you go, if it's not broke, don't work on a fix. At least it will give you time to save for the Heiland LED head!

Oh, it's a grid, not a bulb, never mind!!!

If grid, check the grid lead connections carefully... If you know how to safely, get a AC voltmeter and connect to the grid connections, safely turn on power, and there should be at least a few to several hundred volts AC on it...

But you said it's working, so don't worry about it... The grids are good for a long time, but as mentioned, the power supply would be an issue first, but until then, happy printing!!! :-)
