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...

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!!! :-)

Having similar problem. The green tube quit working on my Zone VI VC head on my Beseler 4x5 enlarger. I've searched for a replacement tube but haven't had any luck. So, I'm looking for a replacement head, namely an Aristo VCL4500.. Anyone have any ideas.. The Heiland LED head sounds like a nice solution.
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 .
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.

I have a Zone VI VC head for Beseler 4x5, and 5x7 and 8x10 Zone IV type II enlargers. I use a Metrolux II timer. I got this stuff from someone that bought it and never used it. Amazing equipment. I plan on using this equipment for many years to come. Nothing better. The 5x7 is on standby right now as I use the Beseler for 4x5 on down and the 8x10 for 8x10 and 6x17. The negative carrier in the 8x10 is better than anything else I have every seen for 8x10 negatives. I hate glass carriers. Best Regards, Mike
