I’m been looking everywhere in my area for a place to buy unfiltered black lights (24 inch bulb) with no luck so far. I’m trying to build my very own exposure box and the only thing left for me to find are the black light bulbs. As I understand it, they look just like normal fluorescent bulbs? Thanks in advance for any info!
Yep they do look like normal fluorescent bulbs except when they’re turned on the light is bluish. You can try buying them online if you can’t get them locally at stores. You’re average hardware store will probably not carry them. I think Topbulb sells them online.
