LED Aquarium Light, 24/7 Full Spectrum Dimmable Submersible Light 36-42 inch 36W for 30/35/40 Gallon Fish Tank, Day+Night Mode DIY Timer Auto On Off, High Brightness 8 Colors RGB Mode

Though the price is nearly the lowest on Amazon for a planted aquarium light, the 24/7 mode is the best yet. The CRI is 93(!), while far more expensive competitors offer 85-89. These lights employ gradual changes during the dawn-to-night cycle (not 3-minute transitions or abrupt switching) which will most likely add to the comfort of the crabs, shrimp, fish and crayfish in the various tanks and paludariums. The instructions are basic for the somewhat advanced controller, but once mastered it's easy to use. Definitely a product worth recommending.

I like this lght

I ordered this light because it has the 24/7 light setting feature like some other similar lights I own and love. This light uses more blue and no red at "dusk" hours which is the only difference I can tell so far. The initial setup instructions are printed on the back of the on/off switch and are clear to understand as are the instructions in the written booklet. I was very disappointed, however, to see that even though the product listing advertised the light as submersible, the FAQ sheet clearly states that it cannot even be immersed in water and suggests you put a cover on your aquarium or put the light on a stand to avoid splashes. This makes this light inferior to other similar lights that can be purchased. I was planning to use it as the main light on the new 20 gallon tank I'm setting up, but now I am reconsidering.

The 24/7 setting is the best!

This product starts out with a lie and has very poor quality. It is NOT submersible! LED does change color but that is the only accurate thing about this listing. Save yourself the hasel and buy a better product.

Muy bien, buena iluminación

Nice and small lamp...

I love love love this light. Setting the time and using the 24/7 light is so easy. Easy to install and the light is all around amazing. The brightest setting is so crystal clear and love the way it makes my tank look.

Gutes Produkt. Ab 61cm Größe ist nicht richtig .das eigentliche Maß wäre ab etwa 57cm . Hab diese Lampe auf gut Glück gekauft und gehofft das sie bei 60 cm außen Maß passt . ( Juhu sie passte) Durch die 28 W und diverse Programmierungen von bis /h wie auch die 24/7 , ergibt sich ein weites Spektrum an Licht und an Stunden die man programmieren kann . ( Zeitschaltuhr ist so mit hinfällig) Produkt ist besser als gedacht !!! ( Sehr hell im normalen Modus ) 👌👍

24/7 h Steuerung ist toll aber lange.Falls Algen kommen werde ich auf 6h tagesmodus und 2 Stunden nachmodus zurück stufen.Gerät passt. Gerne wieder

sieht hochwertig aus super licht der versand super schnell ich nutze das licht für meinen wachtelstall

Es ist Pünktlich angekommen ich habe bis jetzt keine Schlechtes gefunden
