hygger 9W Full Spectrum Aquarium Light

 Por el valor de la lámpara es muy buena , muy elegante y de gran calidad. La sigo probando y cumple sus funciones al 100

Las funciones de luz estan padrisimas!!

these are really cool…turn them on, set a timer (ours is 12 hours), then the lights go off and come back on the next day at the same time. a lot cheaper than a new hood. these are multi colored light. pick the combo you like!

Star ratings explained:

BRIGHTNESS FUNCTION – five stars because it is bright! Very bright!

TIMER FUNCTION – ZERO STARS Whats to rate???? It’s a OFF timer like the Sleep function on your TV in 1972. Not a feature to brag about man, more like pimple your trying to hide. Heres the feature: You can turn it OFF in 3 hours, you can turn it OFF in 6 hours, and wait for it……you can turn it off in yes…..12 friggin hours. NICE. Oh yeah AND you can turn it OFF in NOT NEVER! hours. so…..friggin…..cool………..I Wanna do it again tomorrow, yup, press the stupid button again for 3,6,or 12. not programmable captain.

WATER RESISTANCE – ZERO STARS – Its going to be around water, near water or within inches of water right? I dont want water resistance, I want water proof. Its not. I sealed mine up with aquarium silicone around the edges for my case only. I broke the rules. No tank lid and it’s extended like a ballerina on a tight rope, because my tank is a too long for the size i got. My junk is hanging by metal wires one inch above certain electrfying death. The longer one is too long and that is just plain ugly. I don’t buy ugly on purpose. Aesthetics over safety? in this case yes. My bad.

One year of ownership and now I write my review of this light. Why? I thought to myself, this is a good time to write the best review because I have used it, abused it, dropped it on the floor, dropped it in the tank (oops), and it has gone on and off and on and off and on and off over 365 times now!

What I liked.
• Durability
o I dropped it on the floor
o I dropped it in water while lit
o It has turned on and off over 365 times already and still works like new
• Two sets of brackets
o Plastic ones for smaller tanks
o Metal wire ones for extending it to larger tanks
o I needed the metal wire ones.
~ They are stiff and solid.
~ I still used some aquarium silicone to hold the adjustment in place
• Brightness
o No scientific way to measure in my house, but to my eyes, they are bright!
o I’ve grown plants for 6 months now, no issues, but I inject CO2 and fertilize also
o The description of brightness in their ad. See below for what I don’t like.

What I don’t like

• Brightness description on the Amazon page
o Now the description says adjustable brightness and to combine the timer function to simulate day to night. Not what you think. Its an off timer. That’s it. An OFF timer. Nothing more. Not an ON timer. Not programmable. No memory. It won’t turn on in the morning and simulate night to day. You have to do that , just sit there for two hours and press the little button every 20 minutes and just sit there. And wait for 20 minutes. Make it brighter Mr. Sun, go ahead.. NOT. Get the point. Its marketing propaganda. But not a deal breaker. Just buy a programmable dimmer/timer if you want that fancy stuff. I bought one today, review coming soon.

• Dimmer/timer.
o Again, Its not programmable, so its just an off timer. 3 hours, 6 hours or 12 hours. What if I want 10 hours, if its what I need. It’s useless so I don’t use it. I have a WI fi plug connected to it set to come on at 9 am and turn off at 7PM, 10 hours. That cost me 4 dollars. Well worth it, but that is another review.
o No memory recall after power loss and default is WHITE ON 100% | RED/BLUE ON 100%
o Due to above wifi plug I use, it loses memory every night because I cut power to it. So the fish are awaken every morning by the GREAT GOD of SUNLIGHT shining through their little a*** at the peak of dawn!!!! This is an economical light, so I didn’t expect it to have a fully programmable EPROM chip installed with full dimmable capabilities at this price point. Not a negative.
This product is 100% recommended for a cheap, well built, long lasting, bright LED, slim, sturdy, strong and sleek designed LED lighting fixture for your aquarium, planted or not planted. Buy it if you want all that!

Thanks for reading.

I originally bought the 24-30 inch size and returned for the bigger size. Although the smaller size fit with the metal extension legs, the light itself was small with 3-4 inches of space on each side. With the brightness of this light, it will be okay. BUT, I prefer my light to be full length across. The next size up (30-36 in) was perfect, without the metal leg extension.

Justo lo que esperaba una lámpara potente que hace que el acuario se vea muy bien. Es un plus el cambio de colores y la programación que tiene.

Edit: the manufacturer reached out to me and took care of it
I bought this light anticipating to put together a tank at a later date, kind of collecting items for it rather than buy them all at once.
When I received it I didn’t open the box because it was more conveniently stored in the box and I figured it would be fine. But today I opened it and plugged it. The wire connection on the white lights is broken, so if I jiggle the wire it will come on, but the connection is broken. I’m one week after the return date so I am stuck with this, which really sucks.
I’ve used these lights in the past and these connections tend to break over time for me, but I’ve never had one not work right out of the box
Update: they reached out to me, and after some quick messages, got me a new perfect working light at no expense to me, 100% satisfied.
I love these lights, I’m farming rare aquarium and terrarium plants off them, works great. The five brightness settings are perfect for me so I can tailor brightness to species, they grow plants very well
