220v equipment on 208v service
(OP)
I have some uv dryers rated at 220v. Would it be alright to run them on 208v? Should I expect higher currents and a shorter life span?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: 220v equipment on 208v service
If ballasted, such as with metal halide for instance, the lower voltage may also have adverse effects on a switch-mode ballast.
Just get a buck-boost transformer and step it back up to 220V. Shouldn't cost much at all and probably a LOT less than whatever negative effect you might have; either way.

RE: 220v equipment on 208v service
In an autotransformer configuration, a 240:12 will boost 208 volts to 218.4 volts.
A 240:24 will boost 208 volts to 228.8 volts.
Either voltage should be suitable for 220 volt rated equipment.
The secondary winding (12 V or 24 V) must be rated for the full load current. This will result in a transformer KVA rating much less than the load KVA. That's one of the advantages of an autotransformer connection.
