I was comparing a PO and a SMP today by a window and noticed that after just a few seconds the PO was lit up like a Christmas tree but the SMP hadn't altered at all. Clearly the lume shapes are different but is it the same material and should they exhibit the same characteristics? I have to work at charging the lume on the SMP.

 

Hi Ash
Your quite correct, 2008. The green performs better than the blue then?

 

Different colours do glow differently, as this chart illustrates. Cheers, Al

 

Check that out - light beige is BRIGHTER than pure white. Whoda thunkit?

 

Well that explains it. Cheers Al.
