Any light that's strong enough to grow plants 3' above the water is bright. Spillage at the top is just part of the equation, the light shining out of the tank itself is bright.

I'm neither opinionating nor putting down what you are doing because everybody has their own goals and/or usages. I wasn't familiar with the Vero so I meandered over here for a quick see.

But as soon as you said 36" above the tank I knew there were no Vero's in my future.

Lots of luck on your build though, sounds like you got it going good

PS: these Vero's must be selling like hotcakes in Colorado

Since Vero optics are impossible to find right now you can at least use BXRA ES optics on the Vero 18 with perfect fit.

This is a Ledil Brooke-W with the little feet carefully grinded off


Perfect fit


I will post PAR data for one of these with and without reflector later tonight.

I took a preliminary PAR reading of one Vero 18 with the Brooke-W and at 1000ma and 2ft high I got 165 PAR. This was done open air. For reference my old 9x Rebel ES cannon with 6x 6500K, 1x cool blue, 1x red, and 1x hyper violet got 150 PAR at that same distance in the tank with 60deg optics. At 1000ma the Vero 18 is only running at 33% power as it can go up to 3000ma. My goal is 60 PAR @ 3ft from substrate.

I need to find a driver like the LDD that can do more than 1A.

3000???? err 2100 for the 18

Vero 10, Vero 13, Vero 18 can support up to 2x nominal current, while Vero 29 is limited to
1.5x nominal current

LOL- I've already got you covered there. Send me a PM and I'll provide you with an LDD-H replacement that will push nearly 1600ma. Here's a photo of my little A6211 led driver mounted to a custom PcB. The new driver will simply plug in to your existing Typhon/LDD-H combo.


225 Gal, Glass "Reef Ready" w/ dual Iwaki Pumps & 2 Ocean Clear inline filters. Makers 72" heat sink w/ 12 NanoBox V3 led arrays, custom built CC drivers. All controlled by a BlueFish "mini" Led Controller. iAqua Aquarium Controller , and a 20lb CO2 system w/ Milwaukee Ph Controller.

Haha I figured you would already be ahead of the curve, I sent you a PM.

Make that two lurkers. A quick Google showed me that Bridgelux has a 10 & 13 which will be better for me since I'm building a hood and not a pendant. If I use Vero's, I'll still augment with color but it would be hard to ignore the Vero's as a replacement for my bulk whites if nothing else, serious product for sure..

Enough about my lights, I don't want to tread on your thread just letting you know you perked my curiosity ;-)

I am still waiting on a couple of things:

32" heatsink
3x Vero 18 Decors with Ledil Brooke W reflectors
1600ma LDD drivers from O2Surplus
8up LDD board from O2Surplus
120mm fans

I should have everything in by Thursday so I hope to have it finished by next week.

Tons of goodies came in today.

8up LDD from O2Surplus with 3 of his custom drivers which will power the 5600K and 3 regular Meanwell LDD-1000 for the 2700K.


Also got this sweet little board from him which allows you to use manual pot dimming with the Meanwell's. You just add your own 10K potentiometers.


All 6 LED's with a dime for size reference. 2700K Decor on bottom row.


This is a Vero with the optional molex cable for solderless installation. The cable is quite cheap at $1.30.


Cheap 4-pack of fans from newegg which I got for $10. Tested them and they are pretty much silent.


Now I just need for the heatsink to get here so I can measure the enclosure.

So I have been looking at the photosynthesis charts and spectrum of my LEDs and this is what I got.

Combine this chart:


With the blue on this chart:


Photosynthesis chart


Pretty good for just using 2 LED's I think.

So I put together the heatsink and did a test run and the light has completely blown away my expectations. Here are a couple of pictures of the light on my old tank which is getting replaced by the CADLights 50g.







So in this picture the light is 14" from the top of the tank which is 18" high so light is basically 30" from the substrate. PAR is uniform left and right and front to back which completely surprised me. Then again I measured all the angles in which the reflectors hit.

This is with 5600K running at 1000ma and 2700K running at 175ma which is not my desired color.

PAR
Substrate - 100-110
Top - 250-260
105 Watts

I will do much more thorough measurements once my new tank is in place.

nice coverage.. amazing you can see the color tone difference in the lights on the reflectors..

Your "watts" are caculated at the above running mA or just estimate?

The watts are just estimated based on the running mA. At <1A the Vero's are 29V give or take so it's just a rough estimate. I wish I had a kill-a-watt to actually measure.
