Has any one tried these leds?


I was thinking of getting 4 of them to go over my 210G tank. I was hopping it would give me low light. the ones I'm thinking of getting are the 36'' 27w 8000k led bars.

this was his right up.

The REAL Numbers:


A single ReefBar adds PAR numbers of up to 30 (mms) to the bottom of 24 inches of water (light placed 2 inches above surface) and up to 25 (mms) if placed up 6 inches into a canopy.


A few of these bars can very easily become your Primary Lighting. A common goal for ideal lighting in a reef tank is about 90-120 (mms) at the top of your sand. Choosing a combination of colors from my bars is encouraged for best results from your coral.


3 Bars: PAR 90 at 18 inches under water

4 bars: PAR 115 at 18 inches under water and maintains 100 down to 22 inches


For larger tanks 6 bars will fill the whole tank evenly and give PARs of over 100 at 24 inches deep.


Freshwater and Planted tanks require much less light normally so a couple of these would be solid for most tanks.

First off you have to know where this light outputs its PAR which is not stated the description.
Secondly, as you know plants need red light as much as they need blue light. It's difficult to state that this specific led produces enough red light. A light that has little red causes plants to grow long and the converse is, too much red light and plants will grow short. So you are taking a risk if you purchase this light. In my opinion plants grow and look there best when grown in light that simulates noon temperate-tropical sunlight at 5500k as long as the light produces the necessary red and blue wavelengths of light.

you are 100% correct. but I'm a long time reef tank person and cant stand the looks of the 5500k or even the 6500k light so I have to make a compromise with the color.

the tank is for US natives with just cryps and mosses in it. all I'm looking for is something that will grow them reasonably well that looks good to my eyes, and doesn't brake the bank. theirs not a lot to choose from for a 30'' deep tank.

Your eyes, aka aesthetic sense, will eventually adjust and all will look normal. Besides, everyday you see the world at 5500K.

Well I disided to get 2 of his 36'' 7500k rigid bar light to see how much light it puts out. The two of them should put out 3600 lums.

Well I got the 36'' under cabinet light bar instead of the aquarium one.
It's on my 46g tank with some low light plants. For the price it is a desn't light that seems to give off a fare amount of light. I don't have a par meeter on hand so I can't give you any numbers. I'm just going and what and see how the plants respond before I decide weather to by the more powerful aquarium ones. I will post some pics when the light comes on.

How long have you had it? How are your plants reacting to the light?
I was looking at these lights but decided to get the CFL lights for now but if these work good I might consider getting these lights some time down the road

just set up the tank a couple of days ago so I can't answer you yet.
IMO they probably would work better on a shorter tank. my 46 bow front is on the tall side for these led lights. but to be fare the aquarium ones are more powerful.

I just look at these at my LFS. They are TrueLumen brand (from Current USA). I saw them in use on the store reef tanks and looked great. The heat sink built in to the back of the strip was slightly warm to touch and I think I can mount them inside an enclosed canopy with no fans.

The lowest temp color they have is 8000K which should be fine for plants. I will probably use 2 LED strips and a cool white t5ho to provide better output in the red spectrum. What do you guys think?
