HG005-12W

The lights on the cover of my tank quit. Again. I really didn't want to spend another $65+ on a new hood, so I looked around and found this light. It's perfect! I set it on top of the hood where the old light was. I haven't had to submerge it, but it works great out of the water. It's easy to change the settings and brightness, and the timer works great.

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.

Very good light better spectrum and options than the one i put over my 30gal. I like the sunrise option and havent changed it since.Decent price for the wattage imo but i guess a seasoned hobbyist would differ. Wall plug is chunk and in the wayThe suction cups arent the best even after a thorough clean and prep on both contact points

Super cool light. It automatically changes the tone of the color to match nature's colors during the different times of the day. I love watching it and my tank it happy and clear. Sticks on with suctions cups and stays in place.

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...

Ordered May 1, 2023: Adheres well to the bottom of the glass aquarium lid, it's never once fallen in (Aug 2025) The light is adjustable, with 5 levels of white between dim and quite bright, and it holds the brightness setting from one day to the next. It does also have several lighting color options, and occasionally I review them, but don't use them as I just prefer white light. It has shown a bit of condensation, and at times a bit of algae on the surface, which I clean off, but it continues to function flawlessly after more than 2 years. The timer control is a bit basic, but I'm okay with that. It will slowly brighten at the beginning of the light cycle, and dim at the end. The 12 inch light fits a 5 gallon tank perfectly

I received this light 01.28 and was so excited to get it setup and used. Upon installation I noticed that the light was only working for red and white. I reached out to hygger with my issue and spoke with Luna who was an absolute angel and completely rectified the situation by sending me a replacement free of charge!! The replacement works perfectly and and my fish seem to love it. I am super excited about the 24/7 option where the lights change throughout the day. If you have been eyeballing this product just go ahead and purchase it, you will NOT regret it! Thank you so much Luna for standing behind your customers and making everything right!!! Will definitely be ordering from this company again in the future :)
