Beamswork DA 6500K 0.50W Series LED Pent Aquarium Light Freshwater Plant Discus (180cm - 72")

My husband has 180 gallon planted tank. Prior to purchasing this light. Many aquarists with planted tanks seemed to have issues with using LEDs for plants. Frankly, the plants in our tank are thriving under these lights and they are only set at 80%. We replaced a T5 fixture that had eight 3 foot bulbs. The plants are thriving equally as well if not better under this fixture as they were under the T5 fixture.Pros: we purchased 2 6 foot fixtures for the tank which are getting harder and harder to find. Our tank is also a bit older so it isn't rimless. It has 2 cross braces equally spaced so getting four 3 foot fixtures was not an option. Every other option just gets increasingly expensive. For thus reason,we gave the value for the money 5 stars. As an aside, there are plenty of people who still have 6 foot tanks so i emplore manufacturers to keep making 6 foot lights.The legs are great. They are sturdy and hold the light up a good distance off the water but not too far so fast deplete the efficiency of the light.Several viewers complained about the light sagging over the 6 foot span. One reviewer explained what he determined to be the cause. We followed his advise ensuring the legs only provided vertical support and did not try to make them tight against the tank. We've had no issues with sagging.Initially we thought we needed a light with an adjustable spectrum. After reading a million articles about the spectrum needed and reviews on various lights, we decides to take a leap of faith that the manufacturer had designed the light to be the right spectrum for the plants with adjustments needed. Frankly, being able to adjust the spectrum can be a painful exercise in frustration. I have a Tetra Nano on my 32 gal Biocube and he has a 25 gallon hex with a Tetra Nano. I purchased the one for reef tanks, his is for planted tanks. Being able to make the adjustments on those lights is cool but also a pain requiring tons of research to determine what the spectrum should be for each application. I Like the Tetra lights but simple can be a very nice thing as well.Cons: we bought the controller for these lights. It works well and we have no complaints about the functionality. what we do find annoying is the cord length and the fact it goes on the opposite end of the fixture from the fixtures power cord and on/off switches. The cord for the controller could stand to be at least one foot, maybe 2 longer than what it is. We still gave the light 5 stars overall because this issue is really with the controller not the light.All in all, we are very happy with these lights.

I'm running one of the 72" lights on a 100g tank. Everything in the tank loves it. I'm also running CO2, and ferts. I've been able to carpet the tank with pearlweed effectively. Like it so much, I've added another one to really punch up the high-light plants that are going in next. As the light bar by its self, you have either all lights on (white & blue) or blue only. if you add the timer accessory, you can schedule the white and the blues separately. I've got my blues coming on 30 minutes before the whites in the morning, and going off 15 minutes after the whites at night.There have been some comments about the 72" bowing a bit in the middle (its SUPER slim). I experienced a bit of that too, but found that I was able to eliminate the majority of it by loosening up the risers and making sure they don't squeeze the tank edge AT ALL... if they clamp the sides of the tank, that clamping force is transmitted through the length of the light bar causing it to bow down in the middle. More tension = more pronounced droop/bowing... they shouldn't be "clamping" against, the sides. They should be sitting on top... the site supports should be preventing it from sliding side-to-side only. As far as light coloration goes, that's purely a personal preference. Some people like it, some don't.For low-light only tanks, the EA series is great (3 rows of LED's.) for mid-light or deep tanks (24") the DA series is the way to go (5 rows of LED's)

For what it's worth, I was upgrading from a 4' single tube fluorescent light fixture that I got for free. It did the job but eventually I realized I no longer wanted shadows on the sides. That could be a nice thing depending on your preference. Anyway, I pulled the trigger on this light since it seemed like a good value for the money. I didn't want to have multiple lights set up over my 6' tank so I went with a one fixture solution and couldn't be happier with my purchase. I haven't had it long enough to comment on it sagging in the middle but since it's hidden behind my canopy, I won't even think about it much. The only thing that could be a downside is that it is pretty bright. I'm considering finding a dimmer that works for this fixture to dial it down a touch.All in all, I really like this 6' LED fixture.

Light has been great. Low light plants like java fern and another that I don't know the name of have continued to grow well after switching to this from the expensive sunpaq fluorescent bulbs. Tank is 24" deep. I did have a flicking issue after three years of use. The light would turn on, then remain off for 15 seconds, then flicker on/off again. A new power supply was $25 and fixed the issue. I opened up the dead one, could easily see two blown capacitors so if you're good with a soldering iron you could fix this issue for about $2.

I purchased this 72" light to replace the two 36" lights that came with my aquarium. It provides a high level of light that accentuates my fish as well as stimulates my plants. Within 24 hours my plants noticeably reached for the light, after two weeks some have double in height.The LED's are mostly white with a few blue LED's, which can be turned on by themselves to simulate moonlight/nighttime overnight.

Super bright on my 72 inch 100 gallon tank. Hoping it will support algae growth on the rock work in my tropheus tank. Will update my review in a few weeks 🙂 I’ve purchased several Beamswork lights in the past, as well as their timer/controller. Have always been super satisfied, will buy a pent fixture again in the future. For the money, definitely a best buy.
