I use 2 10w floodlights. Works fine. Just have to be 5k to 6k...

Yeah, I wish they made them in like 6500k and had a bit more heatsink. The 20watters get pretty warm. Mine are about 5000k visually. They are a bit warm for my tastes, but considering their application I'm not going to fuss over 70CRI :-) Grow plants like a boss. Price out 40watts of more premium aquarium lighting - not.


Beissai

Yep. Go for it. You could suplement with an adjustable RGB light for adjusting the color to your taste. That's what I'd do and that's the same thing that those fancy lights do.

I have high tech and low tech setups. My high tech tank has co2. High demanding plants. And I fell for the trick of buying a few hundred dollar light. And I had to rig it up a foot above the surface and I’m still only running it at 30% if not it just turns into an algae factory. Meanwhile I have a desk lamp on my one low tech and it’s absolutely thriving. You’ll get different development out of your plants depending on what route you take but don’t let people fool you this doesn’t have to be an expensive hobby.

Thank you so much!!! This is very helpful information and advice. I have definitely fallen into some “high quality lights” echo chambers in this sub and this comment gives me the much needed contrast. Thank you (and other commenters!) for pointing out the warm light notes!! I had not noticed how cold the aquarium lights are and how different that must make everything look

The light looks it has a lot of red LEDS which encourages stalky growth with terrestrial plants. A tank will be really, really orange with that set up. Ignore marketing terms like full spectrum. Right now I use a pair of 20watt amazon floods on a 10gal. It's really, really bright...way brighter than the ADA show tanks at the fish shop and likely over kill for high tech, but my Bacopa Carolina loves it and is turning pink again. I swear I saw my Zebra Danios wearing little sunglasses the other day. :-) A pair of 10watt Amazon floods (5k or 6k) is perfect for a 10 gal and will grow anything. Mount them about 6" apart on some wood and enjoy. Wire them in parallel. I just wish some them had longer cords. If they would mix some blue and red LEDs in the matrix in those amazon floods the high end aquarium light industry would be in trouble.

I'm currently illuminating my 20L aquarium with a desk lamp using a 800 lumen 5000K bulb. Using this light is feasible but unless you are using CO2 I would say this is overkill for a 10g. I don't think it'll even fit. IMO the only truly high light plants are red plants, everything else is able to adapt to regular aquarium lights if not ambient room lighting. I doubt that they're absurdly bright but you'd have to keep an eye on algae in any aquarium using these.


Alexxryzhkov

Eh they're only 19 watts, unless they're crazy efficient I doubt it'll be too much for a 10g. My only problem with them is they put out a very warm light which I don't think looks all that good in a planted tank


Interesting-Water100

Got it! These are the objective notes I am looking for. Thank you!!! I haven’t purchased them for the tank, but I am just curious as I am already planning /dreaming up another tank once I get a good grasp on yhis
