Hey Guys, I have searched for a long time and done research, but just cant find the right thing.


I have about $140 to spend on lighting.
I have a 23" deep tank, 48" across.
and I want high lighting for a planted aquarium.
I want to grow a carpet of dwarf hair grass. and add a few other plants.
maybe some baby tears.


with my tank being so deep, I am looking for something powerful.


I bought the Finnex Planted + that changed colors and had a remote, but I didn't think it was powerful enough, and it was too yellowish.


do you guys have suggestions for something with power? maybe a cool white look.
Should I get flood lights?
or desk lamps?
I want to get my tank going, but am stuck on this.
any help would be greatly appreciated.


thanks!!

My 2 cents.

LED lights are unnecessarily expensive these days. I'm making my own lights and it's going to cost about $30-40 for two rows of 8 foot lights that you can customize. You can buy 16' LED light strips off amazon for like $15. That'd give you four rows of 4 feet LEDs for $15. You wont beat that price anywhere.

I also have a few cheap LED bars I got from ebay that work great. I purchased a 48" Full Spectrum LED bar for about $40ish bucks. Make sure they're half watt LEDs because the .1 watts are worthless. For highlight, you might need 2 of them, but for medium light tanks one is more than enough.

good luck.

Good idea.. Only catch is you have to add at least $25 for a TIMER/programmer for those strips..
and if you go RGBW in 5630smd or other 1/2W leds you need to find a compatible roll (will be more than $15) or 4 rolls, one of each color...
Of course you ca ndo 1/2W for white and .1w for RGB..

Gooooood point. $5 timer from home depot and the color changer comes with the strip. Btw, I'm looking at the LEDMO 5050 RGB 300LEDs strip. You DO have to buy a $10 power adapter (I know...right) so that's $15 more dollars. You'd also have to find something to put this one (I'm using an old blown out hood and just glueing it to the inside of that hood) and that could add another $5. So yea, Jeff right on that hahaha. A little more than just $15 but it's still CHEAP for what you get. Those LEDs strips aren't the best quality but you get what you pay for.

$30 total and some time to make a light. Still a really good deal. I guess it's really worth for me because I'm going to be doings this to multiple tanks so getting 2-3 of those strips and a few power adapters will go a long way. I also already have timers, old hoods to install these on, etc.

Good luck!

$20.40 for 100 3W 6500k star LEDS..
USE 90

Salvaged computer power supply.. free

Salvaged aluminum..

30- 2.2Ohm 5w resistors (over-speced) $15. (3 diodes in series, 1 resistor, 30 "sets" in parallel..)
JUST a really strong "ribbon"....;)

$35 and you now have a 300W LED....

Add timer $10....and wire...

;)

CUT diode count down to 72 and you can use this w/ 4 channels of LED's 18 diodes per channel"

The wizard says: In solution 0:

each 2.2 ohm resistor dissipates 1078 mW
the wizard thinks the power dissipated in your resistors is a concern Help
together, all resistors dissipate 25872 mW
together, the diodes dissipate 176400 mW
total power dissipated by the array is 202272 mW
the array draws current of 16800 mA from the source
split the diodes into 10000k and 3000k and you get full sunset/sunrise and an average k of 6500.........
"Real" diode watts is 176 and w/ an average of say 60 lumens/watt = 10,560 lumens

more than one way to skin a catfish...

This sounds like a good idea,
did you do this?

has anyone tried this and been successful growing high level plants in a deep tank? :)

I know that this is yesterday's technology, but I have two F32T8 6500K fluoroscent tube bulbs over my 75 gallon tank. I have each tube overdriven using a 4 tube ballast to power one bulb.

I have one of Hoppy's PAR meters and at the substrate level I get between 60-100 PAR.

The bulbs cost about $3.00 each, the ballast cost $12 each and the fixtures were found on craigslist for about 5 bucks. Total: $40

Not the most advanced tech, not as energy efficient as LED, but very inexpensive to build and maintain!
