Par readings for XR15

TD13 · Sep 1, 2015

Been looking for par information for an XR15 Pro for a while. Got the PAR meter from the Reef Club and got it myself. The following table is from a JBJ Nano 28 gallon, 18" T X 22"W X 32" D. The light is mounted on the RMS (9" above water) with the 80 degree lens and set at 70%. All readings were taken from about the middle of the tank below the light. Also locations E,F,G, and H are the corners of the tank at sand level. Hopefully you can read my handwriting.

Great job, that's just 70%. You should be able to grow anything in that tank without issue.

I hope so, I'm completely new to SPS and Acros... I have a super stable tank, hoping the lights will make em grow like weeds.

Well with that light you should be more than happy with the results.

Where are you at?! If you're close maybe we could work something out...

It would be great to have a comparison between the two.

Great stuff! Thanks for sharing your findings!

I agree, it would be pretty interesting to see then Prime comparison results.

I know the LFS has a prime set up on one of their display tanks, I'll see if they'll let me check the levels...

Thats great and very nice of you to do. I believe you could help several people make up their minds and also see what they are dealing with for best coral placement. I do not believe anyone has attempted this, but there has been many request. Thank you for all your efforts. I look forward to your findings. Maybe reach out to an admin to make this post a sticky for those interested.

So the AI Prime is no the equivalent product to the XR15, the AI Hydra is. That being said, the LFS doesn't stock them. I started to burn some tips of my coral so I went back to the 120 lens and took the following readings. I realize that I neglected to read the 18k with the 80 lens before I removed it, sorry. However, you can see the lenses on the XR15 make a LARGE difference in PAR.
