Best non-DIY lighting you can get,
Verified Purchase(What's this?)
This review is from: Marineland Double Bright LED Light, 48- to 60-Inch (Misc.)
This light is fantastic. Uses very little power but bright and gives a fantastic look to the aquarium. Shimmer effect is awesome. Plus you can turn the blue lights on at night to see fish at night without interrupting them. Great for my black ghost knife and any other nocturnal fish.
Its very slim and sleek - when resting on the aquarium the top of the light is maybe 1.5 inches from the glass - very low profile.
The only problem - the blue night lights run all day with the regular lights, but are on the same switch, so you cant set a timer to make it so all the lights are on all day and the blue all night, you have to manually switch on the blue to use it. It will be relatively simple to install a new switch to do this, but requires time, parts, a new power supply, voiding warranty, etc ,etc. Would have been much better if they were separately controlled.
I bought the 48" LED for my 4 foot tank, and it looks great, but I sometimes wish I had gone with the 36". It would leave 6 inches "unlit" on each side, but it would give a pretty cool effect I think, and is $100 cheaper. You can get two 36" for the price of one 48." I mainly got the 48" because it is more powerful with more lights and I was thinking it would be able to support plants better. After being set up a couple weeks the plants are doing well, but we'll see how it does long-term.
Also you never have to replace bulbs. On a planted tank this is a major expense if you want to keep the bulbs producing usable light. This light claims to last 5 years before replacement, while most power compact and T8-T5 bulbs say 6-12 months or less, and are all fairly costly. This combined with the low energy consumption of the LED makes it much cheaper long-term.

How are you plants doing now? Interested because i've been reading a lot and it seems like this light falls in the (low to low medium" light on PAR)

Yea I'd agree low to low medium. The thing about these lights for plants is that theyre a more focused beam so you have to make sure the plants are right below the beam.
As you probly know there are a lot of factors for plants so Ill tell you my experience you can decide. I currently have a 24 inch tall 90g with a tiger oscar and black ghost knife...so pretty messy tank relatively speaking aka nutrients for plants. I put root tabs in once every like 6 months, and dose every week or 2 when i water change with seachem comprehensive supplement. I'm successfully growing java ferns, amazon swords, and water onion, some type of tall blade plants, some type of plants that grow on logs/dangle roots free in water, and a red colored type of plant that is on the bottom and not as tall of a plant. Everything grows pretty slow, but definitely grows. I've gotten it so I dont have algae growing on the plants either. Everythings very healthy looking, especially the amazon swords. I'm happy with the setup, ultra simple cheap dosing every couple weeks, dont have to trim plants all the time, etc. For plants that need higher light, i'm not really sure I haventr tried but im happy with what i have for plants
