Russ,
How would you describe the difference between the current powerbrite LED's to a VHO actinic ? Do you supplement your own tank with other forms or just the powerbrites ? How many do you use per foot of tank ? Do you put them in front and back ? And how deep will they penetrate ?

Thanks

Russ,
How would you describe the difference between the current powerbrite LED's to a VHO actinic ?
No comparison between the PowerBrites and VHO actinics IMO. The PowerBrites are running at 460nm and VHO actinic I believe peak at 420nm. I can honestly say the PowerBrites pop with colors I've never seen before. Just amazing.

Do you supplement your own tank with other forms or just the powerbrites ?
I run my tank with 6 x 54w TEK lights. The two outside bulbs are Pure Actinic. The difference is most striking when all the T5's are off and the PowerBrites are the only lights on. The lighting pattern I use is as follows:

10am PowerBrites on
11am Actinics on
12noon Daylights on
6pm Daylights off
7pm Actinics off
9pm PowerBrites off

The Powerbrites being on during the day also bring out the 460nm pop with daylights on.

How many do you use per foot of tank ?
I do use an excessive amount for my tank. I'm running 2 of the power units and 4 of the slave units. My tank is a 75g.

Do you put them in front and back ?
Because of the high numbers I that I use, I run three lengthwise along the front wall and three running front to back (perpendicular to the first three). Since my tank is acrylic, I have eurobracing and a front to back brace centered on the tank. Each of the three running front to back are on the left, center and right of the tank. All six units are placed directly on the eurobrace.

And how deep will they penetrate ?
My tank is 20" tall. There is no question about penetration. They do a fantastic job of reaching deep down and illuminating the sandbed without any problem.

Thanks
No worries. It's all good. Hope this was helpful.

Russ,
Thanks for all the details...really apreciate it. My tank depth is 30" and I would like to incorporate them into a lighting rail which is 7" above the water. Will this work.

Thanks again,
Thane


You're welcome Thane. Let's not get TOO direct with your questions :banghead: 30" of water, 7" of air, I can honestly say, 'I really don't know'. The lights are good, but I've never tried them in the scenario you're describing. That is certainly putting these LED's through a test though.

You know, IMO it is worth trying one unit for $hit$ and giggles. If it doesn't work perfect (I say perfect because it will definitely work to some extent) then you can still use the one unit and strategically place that unit over a sweet acan that might be higher up in the water column. Kind of like accent lighting in home decor. If it does work to your liking, then purchase the rest of the units to illuminate your tank to the hilt.

One other point to note, if it doesn't work perfect, you can probably unload it to someone for near what you pay for it. It'll still be new for all practical purposes. It'll only have been tested for a brief spell.

Russ,
The ones that you place from front to back, doesn't this block your T5 lighting or are they at the same height level as the T5 reflectors?

What are your thoughts of using 4 of these in place of a 12g Aquapod's CF lighting? 2 power unit with 2 slave units totals $212 (this would allow 2 timers) whereas Wingo wanted $400 to convert my hood to LEDs. Is 16 one watt LEDs enough to light the nano tank?

Hey Warren,
The ones I place front to back are as such:

Left side is completely to the left underneath the T5 endcaps. Not blocking any noticeable light.

Right side is the same as the left, underneath the right T5 endcaps. Also not blocking any noticeable light.

Center one is running above the center brace. Because of the light the center brace blocks I normally don't put any high light demanding coral underneath it, so putting the PowerBrite there isn't detrimental to any critters underneath it. When looking at the tank from the front, you can't tell anything is obstructing any light from the appearance of the light in the tank.

As far as using them on the AquaPod 12, I think it's absolutely perfect for it. Seems like it would be a good width and definitely not too deep. Were you thinking of running the blues, whites or blue/white combo? Mine are ALL blue.

16 x 1W is enough to grow mushroom, I think, but growth could be slow. I used to have a 9w on 2.5G and mushroom is definitely growing in it.

assuming your using white LEDs at ~10,000K
16 x 1W = 16 * ~60to70 lumens = ~1040 lm
16 x 3W = 16 * ~150 lumens = ~2400 lm
