Hi, Simple question, I'm wanting to get some UV lights but the wholesalers call them Black Lights - and there is "black light blue" (a dark blue tube) as used at parties etc to make white shine and "black light white" (a white normal looking) which nobody seems to know about. Can somebody shed some light on this problem (pardon the pun). Daryl. [Non-text portions of this message have been removed]

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).

The ones I use are Sylvania Blacklite 350 F8W/BL350. They fit standard 12" fluorescent light fittings.

If your need for a UV light is to expose PCBs, household white fluorescent does the trick fine. A complete 18" white fluorescent light costs $5 at the local Dollar+ store.

The fluorescent light bulbs I found works the fastest and best for for pcb exposure produce ultraviolet from 310 nanometers to 400 nanometers (UVA: 1. Black light Blue (Dark blue in color) on the bulb it will be labeled "BLB". the last batch I got was from "Spencers Gifts" in the mall. it was just like the under the counter fluorescent light fixtures. plug ac cord in AC in light out simple. 2. the "BL" will work the same but do not have a visible light blocker. 3. a tanning lamp will also usially work well. 4. "HID" almps work well also as long as they do not have the UV filter built as part of the bulb. I do not recomend "black light" incandesant bulbs they really dont work well the UV they put out is a lot lowwer then the BL or BLB fluorescent. good luck BoonS --- In Homebrew_PCBs@yahoogroups.com, Robert Hedan <robert.hedan@v...> wrote: > If your need for a UV light is to expose PCBs, household white fluorescent > does the trick fine.

forgot... if you want a little more generic detail on black lights and wher to get some: http://wolfstone.halloweenhost.com/TechBase/bltgen_BlacklightGeneratio n.html#Tubes you will need to copy both wrap around lines and paste.
