I have a zone vi cold light head and zone vi stabilizer. I am wondering if I can replace the cold light tube with led lights. I have seen the self adhesive led lights and the thought occurred to me to line the cold light head with the led lights. So I have two questions.
1.) Will I need to make any modifications to the voltage/watt output from the cold light head for the LED lights?
2.) Will LED lights work with variable contrast paper without a 40cc Yellow filter?
Thanks

You can maintain the same light output with some trial and error. Try using a light meter to see how bright the existing lamp is. Then try to match that with your LEDs.

There are thousands of LEDs with different light output. The specific LED you choose will determine how well Ilford filters respond.

You will likely need to use an LED driver, and not the cold light's power supply, to power the LEDs.

It struck me that a 15 inch flat screen monitor would make a great light source for 8x10 enlarging.
David. And if you've ever been struck by a flat screen monitor, you would know why.
