How bright are the LEDs? I saw one that wasn't bright enough to let the jellyfish change color.

I bought two of these jellyfish and have just tested both bases (I only keep batteries in one) the LED bases both work fine. Very bright color change which is about every second and includes blue, red, purple and green and also a combination of colors. Be sure you are using a name brand battery which may give you better results. I use Duracell. The light is bright enough I could read by it and after a short while of having the LEDs on when switched off the jellyfish glows on its own for a while. I often use mine as a nightlight in my bathroom. If you think your LED is defective I'm sure the company would send you a replacement. Good Luck.

The LEDs are bright enough, and you can see the jellyfish change color very easity.

No, tjhe base is cheap plastic, use batteries for the lights which merely glow, you do not see jelly fish.

The lights of this model only iluminate when you press the button upside. The light is good, but if you use in a dark room the internal light can be see due transparence of the starship disk (plate). I see in internet somne people that paint with balck ink spray the internal part of the plastic to avoid this lost of light. I wait to explain to you correctly, ok? The sound is very clear, whitout problems in this sense.

I bought one of these ones. it takes only 2 hours showing purple eyes and then they change to consistent blue lights. It may be worth to try to charge it using a different usb cable

No they are not bright enough. Even the neon ones are not great. The wet erase are great, they erase fine with the regular eraser, just requires a little more elbow grease.

If you have a nano fish-only then this would work fine, but nowhere near enough light output for corals. (maybe some softies?) I am using one, but as a light over my sump/refugium on my saltwater tank.

The light is brighter than the fluorescent lamps. I replaced all my fluorescent lamps and I'm very happy. I find that removing the ballast at least for me the leds were the brightest. I hope this helps.

Me too, but with a freshwater aquarium. Two of these lights are more than $60 and that is a lot to spend just because the leds "stopped working." Does anyone know what Marineland's warranty is, and if they are one of those companies that goes out of their way to honor the warranty or out of their way to NOT honor their warranty?

It isn't really designed to light up an aquarium, it is only to increase aesthetic appeal by creating pretty blue bubbles. It wont be too big for your aquarium, it would probably look fantastic.

I found that if you have the dust and dawn mode in the e setting (a bright white sunlight with a rolling cloud cover though various color spectrums) that the light would flash bright when it went to the next color. The fish didn't like it. It seemed as if the light was trying to give the colors it wanted but the timer was cutting the power to the light causing it to flash bright colors when it went I the next color. I've found the dust and dawn mode to work best on one color setting. I leave mine on full spectum. The fish seem to like it and the dust and dawn mode lets them know it's time to wake up and time to settle down. It also reduces the stress on the fish from the light cutting on in one flash motion.

Probably not bright enough for a reef tank. Marine land makes one that is reef bright though. If you were using it in conjunction with other lights to fill out the color spectrum and add intensity it would work. Other than that I've been pleased with mine, I did have an issue with it, but marine land had a new one to me in under a week.

They are not that bright. Basically each led light it's as bright as a dome light

The brightness can be adjusted. The factory settings are what I use. Feel free to call them if you need very detailed info.I have two of these and the one currently in use does as described. The sea life is happy.

No, I would say it's definitely not bright enough for corals/live inverts or anything that requires high intensity lighting.

the LED isn't super bright. there are four on the bottom of the plastic tank. the tank seperates from the black thing on the bottom and the led's are in the black part on the bottom that shine up through the tank. I'd recommend plugging it in if you want it to last longer.

Its more of a yellow or even a tad orangish light. It definitely doesn't dim bluish. I've LED lights in the bath that go that way.

Nope. only the sensitivity does. if you do not want the led too bright, try fixing it facing up rather than shining on your floor board.

I've never seen the fish act weird because of the light. But you should only get this light is you have live plants. If you don't do real plants I'd go with a current USA led light.
