Will using 2 LED lights give me "high" light?

Currently using this (https://www.amazon.com/dp/B074WMV7BX..._CRqZCb3QB867T) Beamswork led for my 37 gallon (about 24 inches from light to substrate) but I noticed that some plants don't receive as much light as others so I'm going to get this (https://www.amazon.com/dp/B01KYELCSA..._CQqZCbA3KPZZK) one as well, which is the same one just a bit longer. Will using both of these lights alongside CO2 give me "high" lighting and help me grow those more demanding plants?

I'm no expert....it may help (as would increased duration) however, if the one light lacks the intensity to reach the bottom (24" can be a challenge), then another like it will likely have the same issue. Whether or not this is an issue may be relative to what you're trying to grow on the substrate as some carpet plants may or may not do well.
I know that when I hung a second LED shop light over my 110g stock tank it made a big difference, but that was for floating water sprite.
Since I invest a lot in fast growing floating plants, light intensity depth is of little importance to me.
I hope it works out for you.

Light is roughly additive, where they overlap it will increase the par, based on clownplanteds #s it might bump it from estimated 30s up a bit. Maybe even nearly double because... a 37 gallon 24" high tank can't possibly be that deep front to back, and in fact I'm quite baffled as to how it can have those dimensions and fit a 36" light? So it might be on the low end of "high light" at the front carpet area assuming you don't have hardscape or tall stems blocking the light from the back light to the front of the tank...

I dont think these two will help you get high light, specially at 24 inches. But it can help you to spread more from front to back. I would say these two will put you in at the end of low light to medium light category.

not sure why you'd want "wider" .. but both together over a 12" wide tank ..yea good amount (not super high) and better spread though @ 12" not necessarily needed..



"additive" PAR at the substrate will be around 50..............
