Blacklight can be a generic term for UV globes.
When applied to fluoros, it means more specifically the UV flouros
that have white phosphor.
Black-light-blue globes and fluoros are both made from dark blue Woods glass
that is a UV filter. You can get mercury HID lamps like that too.
Clear UV fluoro and HID lamps put out extra short-wave UV and is no better
for doing PCBs. They're unsafe to look at too (tho they can be cheaper).
