These LED's i show above are for FISH ONLY tank, they are not the right spectrum for live plants. LED's are not really used for planted tanks, Well, primarily, the reason is cost. You can get LED fixtures for growing live plants, but they cost an arm and a leg. And another leg! Very expensive at anywhere from $4-10 an LED, plus costs for heat dissipation fans and heat sinks, and wiring, and controllers, the larger the aquarium the less feasible this becomes.


I would stay with the fluorescent for a planted tank.

I was looking at some led strips with 6500k output ( which I read is ideal or plants) and they are 5m and about the same price as the stuff you showed. You think it would work?

there are several factors that go into lighting.

LED lights with proper Kelvin, Nanometer, PAR & most importantly PUR
Photosynthetically Useable Radiation. It is also known as "useful light energy"


LEDs often make unaware aquarium keepers think that these LEDs will work for their planted or reef aquariums when in reality these LEDs are not powerful enough to keep photosensitive aquatic life. The truth is that there are only a handful of LED light fixtures that can properly light your high light need aquarium.

i would say those LED's would not work, but you can do a test if you don't mind loosing a plant or 2 in the process. set up a second tank with a plant and run those LED's. In my opinion i don't believe they will survive.
but i am far from an expert and do make mistakes, which is why i say to run a simple test first and see your results before you do an entire tank.

time for the 40 gal to get some LED's

i got a piece of aluminum flashing and bent it to size, then sprayed a reflective color to the underside. I left the top white, no need to change the color.

soon it's time to stick the LED's
