Knock on wood the UV light still works in my ‘63 RCA Whirlpool Imperial dryer. Would be cool if there was was a 40 watt incandescent light in blue and definitely would be cool with the blue light at night
You can still buy these bulbs new, but the glass is a different shape and may not fit in all applications. Remember this is an arc lamp and must be used with a ballast, or in series with a 40 watt light bulb to limit current flow.
