In almost every post I want to increase forage. This is to ask some questions from the learned pros on the "added Value" of putting a underwater light to attract zooplankton, photoplankton etc... I have seen my BG sit and eat at the underwater light -all night-. The video below how they'll do it, they come and get a mouthful bumping the light and a cloud of food comes off it just at the end of the video.

[ hey admins can you get the YouTube video to work - I've tried 15 different combos... none work...

Click the link, suggest you watch the video in 1080p to see all the critters! -> https://www.youtube.com/watch?v=i2siUUjtFl8

It's embedded right below this]


The unit works really well, once I figured out which way the photosensitive switch needed to be positioned... whistle

So this is what happened. I made the design and they are in a plan I drew up and acquired the parts for....

Once I had the parts I brought them into the bench to see if the theory would works... so I wired it, went thru the switches to turn it on...

Now this light puts out 1,000 lumen 360 degrees, supposedly drawing 10 watts DC. I tried to right size the solar panel and battery, to run almost all night from a daily charge. The actual fish management theory is that the light will attract all manner of critters, zooplankton, phytoplankton, invertebrates and best of all - vertebrates, to eat the entire ladder! Well, I assembled it last June, set it all up and waited for darkness.

Night fell and I was astounded at the amount of light it gave off. As you can see in the reflection it's still mid-dusk. You can see a bluegill lit up about 10' thru the water...

It took about a week, but once the fish figured out there was a dense cloud of 'food' they would move in and just sit and munch - I put the snorkel and mask on and dived in.

Incredible, I didn't know the pond had fresh water shrimp, but they were zipping by my mask, fully visible in the light (which means the fish can see an eat them). I dorked up and overwrote the video I took, but it was great. Needless to say, it worked from June until I turned it off (manual) during this last bow season. One the dock light facing the water did is attack bugs but then at night those bugs would seek out your blood. With this underwater light, it seems much better, no aerial bugs (But that's another thread).;)

The underwater light under the dock at pitch dark and the illumination from the light. Honestly - I swim at night and this is just so worth it, just for this, this big beautiful bloom of green light! When you're out swimming in pitch dark, night sky, you can see the light on your legs , underwater, from 20'.
You can see the previous dock light on the outer left edge of the dock. Those came off in Oct and won't be going back on there.

The real question is there any research if this will add to the target fish body weight gain or am I just changing when they would eat the forage already in the pond?

Thanks.

Stressless, my videos aren't showing up today either, so I checked your post, and it's nothing you're doing wrong. It must be a server burp.

Very nice. My son gave me most of the parts to do this but I haven't tried it yet.

Love it. We have a soft spotlight on the dock already, but nothing underwater.

Light does attract fish at night, mostly because it attracts their prey. My totally amateur guess is that this can actually increase fish growth in the locale of the light, as it attracts food. Easier to see and slurp down stuff in the light than chase around for it in the dark.

But I'm often wrong, so maybe an expert needs to share. I'm not aware of studies on this question, but surely there must be some.

Thank you for adding one fuse in your setup.

Also, what type of battery is that? And does your PWM charge controller "understand" that type of battery?

HIF'er,

So yes, the fuse is in line with current from and to all power.

This Y-Solar PMW is shuts off load when battery voltage drops below 10.4v. I plan to upgrade the solar panel from 20w to 50w and the storage from 11Ah to 35Ah. Checked it last night ran about 4.25 hours nice sunny day in OH. I want to get the light to last dusk to dawn mid Apr - late Aug, sequential days in OH with > 13.5+ hours of sunlight. (For simplicity I'll use 10 hours of charging/day and 10 hours of draw per night) input voltage, clouds, rain, temperature etc all factor in but this will get us within the margins.

Charge-
Currently:
20w charge for 10 hours, 200wh, 12v = 16.6Ah on a 11 Ah battery

Upgrade:
50w charge for 10 hours, 500wh, 12v = 41.6Ah on a 36Ah SLA solar battery


Draw-
Currently:
10w draw for 4.5 hours, 45wh at 12v = 3.5Ah on a 11Ah battery. (I am assuming that the PMW is shutting it down at 10.4v)

Upgrade:
10w draw for 10 hours, 100wh at 12v = 8.3 Ah on a 35Ah battery so with the update it should have a comfortable margin, plenty of stored Ah.

Of all the things I need to do and haven't is confirm/measure the a DC power draw in watts of the LED...


Might seem like a lot, but to run shore power down there, +500 yards, it's over $4,500, plus the monthly power bill.

All the components, totaled up (upgraded version Mark II) comes to just over $200.00

Sless,

This project is a good use case for PWM. I would agree your LED uses 10watts continuously. There are other loads like the controller, internal resistance of the battery, etc. The 50 watt panel upgrade and the 35 AH battery upgrade will also do nicely. If your controller is shutting off your system at 10.4 volts, you are hurting that battery if it is LA. Other chemistries will vary.

About your calculations for energy produced, you will not get full rating for 10 hours. Full rating is based on 1000watts per square meter which is only seen around high noon. Also, PWM controllers do not capture rated wattage EVER. It is just not possible. So your 20W panel will make at most 15watts using quick math. From there, it goes down earlier and later in the day. Expect 50% for 8 hours. It will be a lot closer to your actual production.

I will be interested to see how the newer setup works. I would also adjust the protection voltage to something closer to 12.2 volts so as to not damage the battery. With a 35 AH battery, you should be able to see 10 hours of use out of that 10 watt light.You will be burning closer to 15 AHs during that time leaving you with more than 50% SOC remaining.
