PAR Readings Of Our LEDs!

[Reef Breeders]

The PAR readings were taken and updated with the 20% added for spectral correction as specified by apogee here:http://www.apogeeinstruments.com/quantum/spectralresponse.html The bridgelux value fixture: 3" below the fixture- 2160, 3" below the water- 720, 6"- 420, 12"- 336, 15"-252, 20"- 200

Economy fixture (18"): 3" below the fixture- 1440, 3" below the water- 648, 6"- 450, 12"- 315, 15"- 275, 20"- 220

Okay, we just tested the bridgelux value fixtures, and the readings are as follows: 3" below the light-1800, 3"below the water- 600, 6"-350, 12"-280, 15"-210, 20", 165
The 18" economy fixture will be posted in half an hour or so, I will make an animation.

I thought for LEDs you are suppose to use a lux meter as par reading on LEDs give a false reading

They give about 20% below, we did not add the 20%.

A lux meter wont measure useable light where a par meter does.

Guys please do not make this a debate.

Here is the graphic that we made for the readings, it will likely be updated with a better photo. This is for the bridgelux value fixture, which is $199 shipped. This fixture is definitely the best bang for your buck!

Is it dimmable? I'm asking because I'm looking for the lights for my biocube 14. Thank you

 

[Reef Breeders]

Yes it is, here is that thread: https://www.reef2reef.com/forums/reef-breeders/85925-introducing-reef-breeders-value-fixtures.html
We also will have PAR38 bulbs, their PAR readings will be out next week

We just tested one of these over a 40 breeder, and with one unit, the par around the edges is about 80, and towards the middle on the bottom, 200. Halfway up in the middle, it is 300, more results will be posted, for an sps tank, 2 units would be reccomended for a 40 breeder.
