What light spectrum (k) are these LEDs? Is it enough for a planted aquarium which requires 6500k?

Not sure but I would say at least 5K they are very bright. It is almost blinding at night. I may remove some under hand rails. I had a section that went bad and back wired it, however they are installed bent backward backlighting through a poly fountain basin. Worth the money!

These are a little bluish, maybe around what you're looking for. I'd guess that they're a little higher than 7000K. Felix is correct that these are very bright when run at ~13.5 to 14.0V, I run mine at 13.8V. Lahiru is dong something wrong. FYI, if your strip is longer than, maybe, 10' I'd run the supply wires to both ends. If I ran the full 30' strip I'd run the supply to both ends and the middle. Why? Because there will be enough of a voltage drop along the copper traces on the strip that the LED's on the end will be noticeably dimmer if you only connect to one end.

Are you trying to grow real plants -- is that your concern? If so i dont think leds are suitable for that no matter the watts per gallon because they dont produce the wavelengths necessary for plant growth like flourescent bulbs

I have a 55g aquarium and I bought two. I would recommend that you buy three for a 150g tank. There is definitely enough power to the lights as well. I have mine set at 30% whites and 45% blues.

From what I have read these meters do not accurately measure LEDs. I have LED lights and the meter reads 4500 to 7000 lumens but as you say that is a focused spectrum. My plants spend part of the day in natural light and the readings are much higher in the greenhouse.

They are 3700K, a cri of 90 with 1260 luminaries (this is the amount of color rods that your eyes pick up, hope this helps :) These are great they are full spectrum the coating is what filters out the light bringing it up to 3700, if you take the coating off it would be only 2500k

This light should be more than sufficient for your purposes. It is very bright and works quite well for plants. I no longer have an aquarium, but last spring I set it up for our garden starters; the plants under this light did much better than those under an ordinary full-spectrum light. I hope this helps.

These are LED lights. You need HO or fluorescent lights for a planted tank.

I've had the TT-AL09 120w for over a year now that has just the blues and whites. I agree with GCO and definitely look at a full spectrum fixture if you will have light hungry corals. I hope TaoTronics considers building a full spectrum light again.

Should be a clean bright light same as cool fluorescent bulb, not like a warm light. There can be a slight violet tint depending on contents of aquarium

It depends what you are looking to get out of the fixture. The blue bulbs are geared mire towards saltwater. The colormax is more for freshwater plants and the white is just a normal daylight bulb. So what you have in your tank should decide for you pretty much

Light is 6400k. I used it for black pearl peppers and it was fabulous! Hope this is what you were asking. Don

Hi Tim, I can't answer your questions--I don't know about the technical specs. All I know is that I bought a dozen of these lights for my fishing vessel, and the lights are terrible. Very weak compared to a, LED I'd previously installed that was virtually identical in appearance. These are cheap knock offs, a rip off. Don't buy them.

Hello, These fixtures were designed for agricultural purposes and come with 6500k lamps. Not sure how well they do or don't work in regard to aquariums. Wish I could help more. Thanks & please remember to shop with Healthy Harvest Florida!

It would be more than sufficient for your situation. You'll need to be cautious to acclimate your corals to the LEDs. Start out with them very dim, and work up over a period of a couple months. I'd also suggest getting your hands on a Par meter (maybe from a local reeding club). Then you'd have statistical data as to how much light you're getting with each setting in various parts of your tank...

They appear to be bridgelux led's, 3 watt. Two fixtures were too much for my corals on a 90 corner overflow. Presently running One fixture 30 inches above the water, and everything is happy.

Not all of the white LED's appear to be the same color, and I did not see any documentation regarding color index. However, the whites appear to be in the cooler range, so I would suspect most are 6500K down to maybe 5000K.

6500k is like bluish color a little less bright, 5000k is sunlight color more bright
