The answer is always Radium

Something doesn't add up.
PUR is a sub-set of PAR and seneye measures that in % of PAR.

SO 1118 PAR and something like 75% PUR.
IF one did the math so to speak that would give you a PUR # of 838.5

Your PUR numbers are odd.
LUX numbers?

Ah - you spotted my deliberate mistake

Yes it was Lux

All these bulbs will take some time to break in. Running them for only a few hours isn’t going to give you the true color the will produce. Maybe give them a little longer before switching them out. I would say 3 days minimum.

The reef brite has been running for months. The new bulbs I will follow your advice and keep in for a few days. The PAR readings were taken after a few days.
