I also think it will be hard to notice the loss of colour or par, in a bulb as it ages. The best test, seems to be a new bulb beside one of the older ones.

I run a lower "K" 400, in between my pair of Radiums.

your right on this but the best indicator is coral grow and color if they slow to grow and shift color I tink it will be more than time to change the bulb and then I will know I should have change the bulb two month early or someting like this

but from the difference compare to the m135 intensity I could tell you anyway I will be able to know at least when they will be there cause the differance was realy big

wath confuse me the most is your test compare a pulse start to the agro
to my eye it is a major difference and Sanjay test result are very different either? lightning is a realy comfusing part anyway

I suspect that bluwave ballast dont use regular m135 ballast cause the result I get was realy not good with a M135 I have never see those
bluwave so I can't coment on them the one I have try was a Venture m135 pulse start

how much cost that PAR meter do you have? it could be a nice toy to play with

It is a nice toy to play with and we travel.. just buy the ticket and we will come test your tank seriously though they are close to 200.00 by the time you get it in to canada and pay all the fees, then you also need a multimeter that will measue acuratly in the mV range.. so I think I am close to 350.00 to 400.00 for what I have. (Hmm could have bought my M80 ballasts instead.... )

I think Adam's ballast was a regulat 400 watt PFO and not a pulse start..
