Does anyone have the par numbers for T5 actinic bulbs.

How many bulbs, mounting height, fixture/ reflectors, tank depth, and where in tank you want to measure ( bottom/ top) all matter… impossible to answer with just thisDoes anyone have the par numbers for T5 actinic bulbs.

BRS made a good video that shows the par for every ATI bulb.Does anyone have the par numbers for T5 actinic bulbs.

I'm not finding it.BRS made a good video that shows the par for every ATI bulb.
It is weird but I’ve tested every ATI bulb except AB Special. Actinic and Purple Plus lose a ton of output over time where B+ and C+ lose like 10-15%.I wonder why the output drops so much faster than the B+ considering the B+ is composed of a large portion of actinic.
Here you go. They tested specific PAR for all the T5 bulbs.I'm not finding it.
If you have a link to the specific spot

Looks like the actinic bulbs are about 30% less par.My goal was to drop the par numbers I'm getting from my 6 x 24 watt T5 fixture. With this fixture it's 2 bulbs, 4 bulbs, or all 6
With a pair of Reef Brite XHO strips on each side and using all Blue + bulbs I'm getting par numbers higher than I want when all 6 bulbs are on, but lower than I want when only 2 bulbs are on.
I could use just the 4 bulb side, but would prefer to use all the bulbs and get the wider spread.
I thought going with a few actinic bulbs the par numbers would be less than the Blue+ bulbs.
Raising the fixture higher in not an option.
Wow that tank must be BLUUUUEEEEEE.My goal was to drop the par numbers I'm getting from my 6 x 24 watt T5 fixture. With this fixture it's 2 bulbs, 4 bulbs, or all 6

Different strokes for different folks.Wow that tank must be BLUUUUEEEEEE.
Why would you even care what my tank looks like.You use 6 blue plus bulbs with 2 xho blue? That must look horrible. What is there even to look at in the tank?
Thank-youAfter the burn in period, actinic bulbs have PAR close to the Blue Plus. I don’t have the link handy but will see if I can dig it up
Edit: I think this is the link. Go to the charts for the readings. After burn in is surprising to see

I have a Apogee MQ-510 to measure the par.The output will be slightly less with actinics. A decent apogee meter will have been optimized to be able to read wavelengths that short without much error. A decade or two ago, and it’s a different conversation but they’ve improved to read deep violet light very well. But yes, the output is slightly less. Visually much dimmer. Can you not also raise the lights higher to reduce intensity? Are your leds dimmed or just on/off?
