Reefbrite xho blue par

[pjr]

Just checked my xho’s using an mq-500 sitting 12 inches above the tank.

At water line: 120
6” under: 72
12” under: 50
22” under: 40

Really? That seems awfully low.....

@Salty....I also have a Lux meter because of reading your threads on Lux to par conversions. I’ll take a reading of par and lux tomorrow in hopes of strengthening your conversion works.

It is what it is. Not sure what to tell you. I love the xho’s but they don’t do much besides adding a nice blue light... I really like them.

Cool thanks. I metered at 12in fwiw.
Just need the lux really. Prob devide by 70.
I’ll probaly go see a friend who has them. I’ll need to buy beer now. Lol.

@saltyfilmfolks Here is the reading of the xho’s at a little under 12” at 100% The picture is a little hard to read, it is 102.

 

[taj0930]

How would that be effected in water?

 

[Syntax1235]

@taj0930 I’ll measure 4” above frame of tank. I’ll take reading 6”, 12” and 22” under water in an hour or so.

 

[taj0930]

OUTSTANDING! Thank you so much!!

Thank you.
Is that 102,000 or 10,200. I can’t see the dial lol.

 

[Syntax1235]

Ok here are the numbers:

At water light line with Halides 4” above tank: 1900 par. (Reading was take. With the probe just above the line. The picture is not when i took the trading.

6” below: 650 par

12” below: 400 par

22” below and off to the side due to rocks: 300 par

On the 100,000 setting, so 102,000

What was it w just the reefbrites?

 

[Syntax1235]

What was it w just the reefbrites?

yes, only xho's.... the par measurements were with halide only at 4" above the tank

Closer to what I got a few years back.
A single bar gave me 40-45,000 at 12 in.

That doesn't seem close to me?

 

[saltyfilmfolks]

I metered a single.
X2 would be 80,000 to 90,000.

 

[taj0930]

I’m so confused. I thought it was read 102 @ 12”? How did the par jump to 600 measured in the water at 12” + 4” to the the light? Am I really blasting 600 par to the bottom of my 20 gallon long reef?

 

[taj0930]

Hey so need help understanding all this I guess. How does 90,000 equate to par? Hey guess I’m concerned now seeing par ratings posted of 400 @ 12”? Didn’t expect these to be so powerful I guess. Right now I have 1 t5 blue plus, 1 actinic, & 1 reefbrite xho blue @ full blast about 3-4” above tank. Tank will b lps& softies. Too much par?
