Best MTG2 Driver for Aquarium?

I’ve been using a MT-G2 mounted on a pc cpu heatsink with a fan on it to light up my aquarium. Its been working great till today. The driver I’ve been using is a LD-2D 3A 2-3 Cells Circuit board for 6V LEDs from intl.outdoors. I’m using a 12vdc 3amp ac adapter to power it. I usually leave it on high but after a while the output drops to a little better than medium. I suspected the driver may be getting too hot running at full power all the time. I opened up the little case I made for it and felt it while on high and sure enough there were a couple components on it that were getting pretty toasty. I was going to put some silicone thermal cubes on it but I ended up shorting the -power wire on something now the driver is caput.

So now I’m trying to find a replacement driver. Hopefully something more suited to being left on high all the time. I’d like to eventually stick maybe two more MT-G2’s in the canopy so maybe a driver that can drive 3 led’s hard, would be ideal. I’ll probally have to update the power supply. I have an old pc power supply I can use.

Any ideas on a good driver? I’m hoping to not spend too much. A few modes would be nice.

Why not look at buck/boost drivers?
Look up Julian ILLETT on Youtube

Hmm, I thought you are offering best MTG driver (not sure why would it only be for aquarium)!!!
How one question mark can change meaning of the sentence :slight_smile:

Good point. Title has been updated. Thanks

Looks like already subscribed to his channel. Most of his stuff is over my head, but I’ll search his channel to see if he has a video for what I’m looking for. Thanks

After watching some of his 100w led video, I’m thinking that might be a better fit for use in my aquarium than a mt-g2, and cheaper too. Thanks for the tip.

Use bridgelux vero LEDS it is the best

By the way i have 2 hobbies flashlights and planted aquarium , and i use the vero13 with 5k and 90 CRI leds combined with vero10 3k and 97 CRI on my tank it is the best man

this is my tank but it is under construction

and this is my DIY heatsink

Wow. That’s a beautiful tank. I think you’ve inspired me to go bigger than I was originally thinking. I have a 180gal freshwater community fishtank. I haven’t had live plants for awhile but now I’m considering going with high cri leds and putting some live plants in there.

Thats quite a collection of pc heatsinks you have there. I love how nice your setup is while staying on a budget. I’ll need to do the same considering how much this stuff cost if it weren’t DIY.

How are you driving all those leds? Are they dimmable? Thank you for the great info.

I am using something like this DC-DC 100W Constant Current Boost Step-up Module connecting the LEDS in parallel and powering the driver with an old PC power supply with the 12v output

And lately i have tried this one 150W Boost Converter DC-DC it is cheap but unfortunately it is only constant volt it has no constant current but it is working just great .

And both of them is dimmable as you can adjust the volt and current as you wish
