Red LED clusters put out between 70-100 mW/cm˛ at face position (about 1" distance) depending on the MFGR.
RED fluorescent lamps are typically lower... in the 10-20 mW/cm˛ range.
Both need peak emission near 633nm for skin "rejuvination".
If in any doubt what your output is... you need (of course) a Solarmeter Model 9.6 Red Light Meter!
Welcome to Solartech Hey Stephen: This too is a quantifyable science. Sorry... not simply marketing...
