DIY LED's par

[shawne]

These are my par readings on the DIY fixture that Greg and I built. It consists of 12 cool white, 12 natural white, and 24 royal blues, ran on 4 meanwell 60-48D dimmable drivers. I have been acclimating my corals over the last month to these much higher levels from a 4 x 39w T5 fixture. Everything is doing very well, and even showing some growth from my monti's.

Next on the agenda is todo my son's 33g cube tank, the reduction of heat and water evap over the last month has been amazing. Not to mention the amazing colors that have come to pop out under these lights is amazing to me. Also my purple haze has come back to life and started to grow, the button polyps are going bezerk!

Nice numbers!

congrats
How long and how have you been acclimating corals

Actually just got it put together the same weekend as the last comas meeting, so almost a month now.

Hey Shawne, could I get the par meter back from you this weekend at the meeting?

Another member just bought retro LEDs and he wants to test them. It would be an interesting comparison.

Congrats on the build, nice job.

How deep is the tank and how high are the LEDs from the water. Also did you get a chance to measure the 36" t5

 

[shawne]

Paul- yes planned on bringing it to the meeting.

Matt- 40 breeder, so 18in deep, and 7in off the water. Come by and check it out.

So LEDs are taking over COMAS? I won't be at this meeting, but I would still like the club's par meter. An old friend has a film showing at the deadCENTER Film Festival at precisely meeting time and I told her I'd support. Well, perhaps there will be a break in this full-on LED action for a combo test soon

I'm kind of joining the fun. I added about 150 lower powered LEDs (.2w) for supplementation to my MH/T5 setup a while back.

Paul- yes planned on bringing it to the meeting.

Thankyou very much!

I can't find the site to the real conversion, but the Apogee quantum meter does not correctly measure the light in the 400-500 Nm range. IIRC It actually underestimates the par approximately 20% less than what the actual amount is. So your par readings are a little higher than what the meter shows!

Where did you find this info?

 

[ghellin]

I will look again I think it is in the big DIY LED thread. I couldnt find it yesterday however I only searched for a few min.

I'd love to get in line on these guys here eventually too..


Got my AI SOL Blues coming in this week. Also got the new Apex controller coming at the same time as well.
