Huh

Horrors.... I goofed. Move the decimal point four places left to convert mW/m² to mW/cm² as a 6.0 meter would read (not five places).

So 6164 mW/m² = 0.62 mW/cm², and
So 5214 mW/m² = 0.52 mW/cm².

I was thinking about 1 m² = 10000 cm² and counted 5 decimal points in error.

6164/10000 = 0.62 not 0.062. Sorry.

Point was..... for those of you who have 6.0 meters.... you can see readings from many and varied lamps ranging from a low of ~0.20 up to a whopping 2.00 mW/cm² ... so take the 0.62 (or 0.52) from the Sportarredo HPO in that context.

Having said that... I do not know where on the UVB spectrum the photons are placed, so (as many of you know) if they are left-shifted from "normal" HP then they may provide results equal or better to right-shifted photons reading higher on a 6.0 meter. That's where a 7.0 meter can distinguish the difference.

Thanks to an email from Don pointing out my (rare) math error!
