HG005-10W

Impressive! I’m thrilled with the price and all the fun options. For what this cost, if I have to replace it here and there, I’m still ahead of the game. There is a 24 hour mode that starts with orangey sunrise colors, gets brighter during the day, and ends up fading into blues and then turns itself off OR you can choose your color and increase or decrease the intensity. Very nice product. I turned the suction cups around and have it attached to the glass tank lid, facing down into the tank. It is submersible but that’s not what I was looking for. I’m starting of dim for my betta and will increase brightness in the morning. Very pleased so far.

Actually purchased 2 of these lights. A 12” for a 35 gallon tank, and a 23.4” for a 55 gallon tank and I am pleased with the lighting for each of those tanks. I ended up zip tying them to the under sides of the existing lights which I have turned off. I must say that once we figured out the correct way to set the 24/7 lighting feature, we love how that so perfectly works!! (At 6:00 a.m. we turned each unit on and then pushed the 24/7 button once that lit up the 8:00 (military time) light. Nothing else was needed and the lights started the next morning at 6:00 a.m. and went through the different modes all day long until they shut off on their own around 10:00 p.m. So cool how that works! So far we feel these lights are a great value for what you’re getting. They’re easy, convenient, and interesting to watch the light changes through the day! I’ve attached photos showing one tank at these times: 6:00 a.m., 10:30 a.m., 5:30 p.m., 9:15 p.m.

I've only had these lights for about two weeks, so I can't speak to their longevity. Hopefully they last a long time because I love these lights! I had submersible lights in my 125 gallon tank previously. They were some Chinese off brand that simply had an on/off switch. They were a brilliant, bright white with hints of blue, and since they had a simple switch they worked with smart plugs and Alexa routines. So that being said, the first thing to know about these is that they will not work with smart plugs. Once they lose power, they forget their settings. However I've found using the 24/7 timer mode to be even better. It can be a little tricky to get set because of poorly translated instructions (more on that later), but once you get it it's easy.....and the results are quite brilliant! In the morning, instead of my lights popping on instantly at 100% brightness (which as you can imagine is probably not the nicest way to wake up), these lights begin with a soft orange moving gradually to a brighter orange to simulate sunrise. Then it slowly becomes a dim white light which throughout the day increases in intensity. Eventually the white light begins to fade into a bright blue simulating moonlight, which then fades over time into a lighter blue then darkness. It's a much more natural light cycle. I believe the whole cycle results in roughly 16 hours of different types of light (6AM - 10:50PM). I'm not an expert by any means, but I do not believe this extended light cycle will contribute greatly to the growth of algae because it's not intense white light all day every day, but I could be wrong (again, it's only been 2 weeks). As for the intensity of the white light in particular (since that's in use most of the day), it is satisfactory. I purchased another brand of light before these and they absolutely PALED in comparison to the old lights I was switching away from. I returned those and bought these. These are still not as bright as the old ones but they are much closer and I suspect it's because these are more full spectrum instead of all white. But I'm obviously pleased with them, they certainly are more than good enough. As for setting the 24/7 cycle....just ignore the directions. You'll see a series of times annotated on the controller with an LED light next to them...they are military time so just do some googling on that if you need to (or just subtract 12!). Wait until one of these time frames and push the 24/7 button until the LED next to that time is lit. You're not really "setting" anything....you're telling the controller the current time and it does the rest. If you want your cycle to start or end earlier than the 6am sunrise (the default), simply lie to the controller when you set the time (ie tell it that it's 8pm when it's actually 7pm or 9pm to move the cycle forward or back by an hour - or more). One final thing to note which should be obvious from the picture but I really didn't think about it until I got them in hand.....most of the submersible LEDs I've had or looked at were a round tube secured in rings with suction cups. Because they were round, you could mount them anywhere in your tank (such as behind the rim) and simply rotate them to direct light where ever you want. These are, obviously, not round. So there is no rotating and they will only direct light directly up, down, or across from where you mount them. So keep this in mind when planning where your lights will be in your tank. Long story short, I love these lights and as long as they have a decent service life, I will 100% buy again! Will come back and add photos when I grab some (if I can add them later) UPDATE: I still love these lights, however it comes with a major caveat: I've already had to replace two due to water getting inside of them. I replaced the first hoping it was a fluke.... Now the same thing with another one. I love the lights enough otherwise that I WILL replace again, but this time the "submersible" lights will NOT be going in the water. I advise either keeping your water level low enough that the lights aren't actually submerged or mounting them top of your lids. That will present it's own problems that I have to solve because the glass reflects some of the light back into the room. But I'll figure that out...

I bought this product in November and have been using it in my 3-4G tank since. It is a nice little light that puts out plenty of light in a lovely color. like other reviews said the 24 hr mode isn't the most useful, but I mostly used the 6 or 10 hr timer (I do wish there was an 8 hr option as well). After a few months of no major problems, the light started to have issues with the controller. The buttons stopped working, and then soon the light wouldn't turn on at all. It turned out to be the same problem as others have had where the plastic broke and it was no longer waterproof. This all happened right after the return period ended, so maybe try a different light. UPDATE: I emailed the company and they were very quick to respond and send a new unit. I will just be very careful to not bump the front of the light and hope for the best.

This item works well and has full spectrum lighting as well as sunrise and sunset modes. The suction cups work well. The instructions are a little hard to understand but trial and error always works eventually. Good quality and a good price

Muy buen producto, buen costo. Hizo mucha diferencia en como se ve el acuario. El modo de 24/7 tiene su truco’ y es encenderlo en la hora que indica y dejarlo con la luz led que enciende y apague. Ya el día siguiente verás que funciona. Al momento todo ok. Very good product and good price. It made a big difference in how the aquarium looks. The 24/7 mode has its trick: you need to turn it on at the correct time and let the LED light turn on and off by itself. By the next day, you’ll see it working properly. So far, everything is good.

This light is worth it!!! I truly LOVE how it can be put on the automatic setting, where it goes through sun, rising, full sun, and then evening, before shutting off completely for the evening and then coming back on the next morning!!! I absolutely love it. However, I will agree with everyone else.: it says submersible, but do yourself a favor and don’t do that!! it will last for a little while if you put it underwater, but it will eventually stop working. So just keep it above water to do yourself a favor. Yes mine stopped working, but I love it so much that I’m just going ahead and buying another.

Good one I received nice light good work hygger

Excelente equipo

it is a unique aquarium lamp in the world, you won't find in any store any lamp like this one, it simulate the 24 day light during the day, it is perfect. I have a year with the lamp and it work perfect. If it get damage by the long time used, I buy it again.

Good

Worth-it. The suction holder is not good. Better use a double sided tap for hanging. The 24/7 light setting is awesome.
