What the AI looks for in Black Light Bulbs
- Wavelength
- 365 nm for strong fluorescence with little visible purple; 395 nm is cheaper but shows more violet light and gives weaker effects Wavelength separates a real black light from a purple party bulb.
- BLB vs BL
- BLB lamps (dark filtered glass) are for viewing; BL lamps (unfiltered) are for insect traps BL lamps emit a lot of visible light and wash out the glow effect.
- Bulb vs tube
- Screw-in bulbs for spot effects; tubes or LED bars for even coverage of a room A single screw-in bulb only lights a small area.
Brands that matter
- Feit Electric: Common screw-in black light bulbs.
- Philips: TL-D BLB fluorescent tubes.
- Sylvania (Ledvance): Blacklight-blue fluorescent tubes.
What to avoid
- Bulbs that do not state a wavelength
- Staring directly into UV sources for long periods
