You need a UV (UltraViolet) lamp. To be precise, you need a shortwave UV lamp (many countries use long UV as opposed to short). Most, but not all, tagging omitted errors, are rather scarce. I once checked several thousand stamps for my brother and not a single one was untagged.

JLLebbert and Others,

I just bought a 16 watt UV Field Lamp from UV Tools. It came with shortwave and a longwave bulbs. Which one should I use for Great Britain stamps? How about USA stamps too?

Thanks,
Jack Kelley

For US stamps, definitely short UV. While I think the same is true for British stamps, I could be wrong. Maybe a British collector will chime in.

According to the following link, for British stamps it is long wave after 1992 and short wave before 1992:

Some UV lamps come with both an a switch to toggle between the two.

Thank you both for your input. I'll be needing both as I collect UK up to the year 2000. Davo Hingeless.

Jack, all of this UV stuff is sometimes complicated, especially if you collect foreign counties.
or the US however all you need is short wave ( SWUV ) for tagging. Long wave ( LWUV ) is useful if you like to distinguish between regular and high brite paper or when looking for repairs or other irregularities
