Ah, 1*10-9.

I have two. one as back up.

My last one broke after about 12 months of service and i bought two replacements just in case...

Best thing is too shine them on coppers when they are wearing them highly reflective yellow jackets. stands out for miles!

i just looked a nanometer is 1 billionth of a meter

1*10-7 metres i think.

distance yes, but obviously a nanometer is an incredibly short distance.

wavelength meaning distance or the way it works?!

must have hurt being blinded :o

it's the wavelength, that being the length of one whole cycle of the emitted light.
