Which marineland led

I recently purchased a marineland 24" cube and am planning a low tech planted tank. I really want to minimize heat in built in wall installation, so I'm going led, and don't know if the marineland double led puts out enough light for beginner type plants or if I need to go with the newer planted led which might actually be too much light and cause alge. Am I going to have dark spots with only one light bar across the top of a square tank? Any thoughts or recommendations appreciated.

The double bright led will work for beginner plants just fine since it puts out lower light. You may want to check out the finnex LED fixtures as well. The fugeray has a lot of little leds which seems to eliminate any spotlight effect or dark spots, IME.

This thread here shows a lot of the different PAR values for many LED fixtures. LED Lighting Compendium

I have both a double-bright strip and the new "planted tank" fixture or whatever they are calling it.

I am working on hanging my fixtures and took PAR readings this weekend. The planted tank fixture was easily into high-light at 24 inches above substrate and will grow you plenty of algea in a low-tech setting.

A double-bright would be more suitable for low-light. I have only used these on a rectangular tank yet and cannot speak on that issue.I haven't used a finnex fixture yet, but they seem to be well review, and I would like to check one out.

The marinelands, when perched on the tank instead of hung higher, do seem to cause some spot-light effect. Otherwise, I am a huge fan of LEDs after using flourescents. I have a small DIY LED set up for a 10g using strips of lots of smaller LEDs. I like the even coverage this provides, and as a result, might lean towards the finnex fixtures in the future.

IMO, you are going to get poor front to back coverage with a single doublebright light.
I've got one on my 18" cube and I find it really only provides effective light to about half the tank, leaving dark bands front and back if I center it.
For a 24" cube I'd strongly suggest using two doublebrights if that is the way you end up going.

I'm right there with blink. We both have the Marineland 27 gallon cubes and the double bright didn't provide well enough coverage from front to back. I have replaced mine with floor lamp that I am going to attach to my tank stand when I move next month as it provided better light coverage for the whole tank. If you do go with the double brights, you are going to want to double them up.

Thanks much for the information. I've been also thinking about one double bright led and then maybe a single strip or two that attach to the rim.

Bsponsler: If your 24" Double Bright fixture is any higher than a foot from your substrate, you aren't going to have anything beyond the lowest of low light, in my experience.

Your money will definitely be better spent on a Finnex fixture or something like daylight CFLs (if you really want to save tons of cash).

A double-bright at about 18 inches keeps me comfortably in the low-light range for my non-co2, low-tech set-up. I agree that you may need to double-up on a cube, and that research into a finnex fixture is probably worthwhile.

If you have the money to invest in one, I would recommend purchasing a PAR sensor for a multi-meter. Best piece of equipment I have purchased since keeping planted tanks, and you won't be left guessing on light intensity and coverage. I was running CFL fixtures before purchasing one, and was surprised to find the CFLs were putting me into the high-light range. I think the PAR readings are critical for any DIY build using CFLs.

Get a Finnex Fugeray before you buy 2x Marineland units for 2x more money.

Think I am going to start with the finnex and see how that does. Thanks to all for the advice.
