***Please Note:To produce a glow in the dark effect, you need a UV bulb with a wavelength around 365nm which is considered the optimal range for most glow-in-the-dark pigments, often referred to as a "blacklight" bulb; most commercially available glow-in-the-dark bulbs will emit UV light within the 385-400nm range.
Key points about UV ratings for glow-in-the-dark bulbs:
Wavelength matters:
The most important factor is the wavelength of the UV light emitted, with 365nm being the most effective for making most glow-in-the-dark materials glow brightly.
UVA range:
Glow-in-the-dark bulbs typically fall within the UVA band of ultraviolet light.
"Blacklight" designation:
When looking for a glow-in-the-dark bulb, look for one labeled as a "blacklight".
