Philips WHAT? Old-era peaking at 350nm or new era at 365nm?

Makes a big difference in 5.0 readings.

I can't keep track of which brands/models of lamps are old or new era anymore... but the new-era ones sometimes say "HP-like" output... meaning UVA peak near 365nm like the meter response also does.
