Flood light for shallow 20 gallon?

Hiya,

I want the shimmer from a pendant, and at least medium amounts of light for my 90x40x30 (36x15x12") shallow tank. I'm going back and forth if I should go for a HC carpet, but at least I want to grow AR mini. Initially I were thinking of 2x Kessil A80 + controller, quite fond of the silent operation of them and general appearance. But that adds up to ~500 USD, and the other expenses related to the new tank is rougly the same. 1000 USD seems a bit mental to be honest...

Anyone with experience of these sort of lights? I mean, two of these would add up to a tenth of the Kessils. They may not have the possibility of scheduling sunrise, but is that really worth 450 dollars extra?

15W RGB wireless controller

9W spotlights
https://www.amazon.co.uk/Wefond-Land...2&sr=8-78&th=1

30W flood
https://www.amazon.co.uk/Security-Da...5&sr=8-30&th=1

With the above I could build a simple frame to hang them, use a timer + they're able to withstand some humidity. If anyone has hooked them up with a proper controller or got any other suggestions I'm listening.

2 of these would be fun w/ the 2 whites..and RGB..

As to "proper" controller that's a bit more difficult..
you could "hack" the code and build an Aduino based programmer.

finding a ramp up/down function is a bit difficult. Lots of types w/ varying amount of functionality..

Like this one. You can set up an on/off period but doesn't mention like a gradual on off time:

Thanks for tuning in Jeff, I've gotten the impression you're the lighting guru on this forum. Is it safe to think that with those light I'd have a decent shot of growing some medium-difficult plants, and hopefully with the RGB being able to tune in a nice colour rendition? I'm not too well-read on lighting, but CRI at 84 shouldn't be too bad? One concern I have is around the 120 degress beam angle, have you seen anyone modify those to narrow it a bit? I could probably do a DIY reflector solution but wouldn't be that pretty or effective.

I'm not into programming at all, so unless there's an easy hijack I'd settle with just a simple on/off timer. I asked if there's schedule with fading functionality in the app for the bluetooth one, I'll update here if I hear back on it.

Well wouldn't call it easy but not terribly difficult, once you capture the IR codes..
https://www.plantedtank.net/forums/2...ontroller.html
Thought it was worth at least an FYI..


3 Fluval Nanos are ok..


https://www.amazon.com/Hagen-Fluval-...955492&sr=8-82


Shimmer is created from point light sources and surface movement..
So you increase or decrease it w/ either changes..


You just want to avoid a blanket of leds though ANY LED w/ out a diffuser IS a point-ish light source..

Watt wise 1 Nano = 1 A80


Step up would be TMC, a brand not really popular on this side of the Atlantic..

Those Fluval Nano's look like the perfect middle ground! Thanks so much for that. The DIY solutions doesn't seem overly complicated, but I'm afraid I won't be able to buy the exact same products so running in to issues seems inevitable.

The Nanos are awesome! I have ten of them and use them on all my tanks. Note that you can reverse the L bracket to run them higher above a tank if you want.

Great to hear that! I think even my LFS stocks them which is handy as hell. Can you tell me a bit more about the app, can you set a schedule of the day and hook up multiple units to the same schedule?

If you get one (or more), make sure to update the firmware, and name the light. Read the procedure for the firmware update, so you don't accidentally interrupt or re-trigger the update while it is happening, since it is a two-stage process.

Be aware that the light does not seem to have a battery, so it resets its clock to midnight after a power cycle, but I recommend a UPS anyway.

They are IP67 rated, and have a three-year warranty.

You will be able to independently control Pink, Blue, Cold White, Pure White, and Warm White.

The light has three modes:

Manual: Color control and on/off. Use this for photography or if you want to show the tank off-hours.

Auto: Color and time control for five photoperiods: Sunrise, Daylight, Sunset, Night, and Sleep. You can save multiple Auto programs in the app and load (Export is the term they use) a program to any of your lights.

Pro: Color and time control with ten set points. You can save multiple Pro programs in the app and load (Export is the term they use) a program to any of your lights.

Programming Tips:

The interface for manipulating time and color levels can be a bit touchy. For your first new Pro mode program, I recommend deleting all the set points and starting from scratch, as the interface to add a set point is a bit easier to dial in numbers. Once you have done that, the editing is not too bad.

There are some good Youtube videos on this light, and many forum threads here where folks have shared program screenshots.

I personally run two siestas to extend my viewing time so I get to enjoy the tank in the morning, mid afternoon (weekends), and every night, without doing too much light per day.

In my low tech nano tanks, I run one or two per tank, but I don't go above 50% power right now. For my pico tanks, I run even lower power levels. I keep blue pretty minimal compared to the other colors, and pink kind-of in the middle.

I have posted my dual siesta screenshots before, so I will just link to them:

I'm very grateful for you taking the time to post all that information Streetwise, it's really helpful for me. I've definitely decided to go for those Fluval Nano lights, I was even at my LFS earlier today but they didn't have these specific lights. Good idea with the siesta, I'm gonna utilize that method too. Nifty to see that you can set different spectrum for different photoperiods, so you can have warm glow to simulate sunrise/set, and then blast some more colours on the day to grow those plants. Again, big up for your helpful post.
