If I could give it 10 stars I would I’ve had it for a little while and it works perfect it was so good I bought another one for my 100 gallon tank it had fast shipping too

These lights are great for the price. They have good spectrum, with two separate channels, a blue channel and a white channel. The light comes with a remote that will work with multiple lights if you need more than one light. The set up is pretty easy, if not very basic. You can set intensity for each channel along with on and off times. These lights don’t ramp up or down so I use a secondary light to simulate sunrise and sunset. These are well made units that don’t feel cheap at all. Recommend for budget conscious hobbyists.

I've had some high-end saltwater lights. This for the price is bang for your buck. Does the job. Saltwater corals did excellent under these lights

Deceptively very powerful, recommend starting around 30% on the power cause you can really cook corals with this. Color is great.I ran it 8 inches about water line for my 125 gallon, while I didn't realize how strong they were, i ran them around 80% and have a massive leather toadstool coral, but bleached a birds nest. Turned it down and everything seems happier.Definitely worth the price, they're so strong compared to super expensive reef lighting. Only downside is you have to build a mount to them if you don't have the ceilings for it, they are heavy and you're not going to find something similar to kessel or radian to mount to the tank itself. Requires a lot of DIY work to get them installed safely.

Tiene todas las funciones que promete, es estética y luz potente

Cumple la función. Esteticamente es un 100. Estoy retomando los corales y estos han estado muy bien bajo esta luz. La funcionalidad de poder ajustar la salida de luz desde 1% hasta 100% me ha resultado muy util pues mi acuario no es muy grande (29 galones) y he podido ajustar poco a poco a los corales a esta iluminación. Los peces se ven muy bien, incluso salen mas a la parte abierta. La luz azul ilumina de forma excelente a los corales y en el caso del gobio de fuego pues tiene ciertos tonos que resaltan muy bien durante ese rato. Inicie el proceso de adaptación de mis corales con un 5% los primeros dias, luego pase un 10%, quedo así un par de semanas y acabo de subir al 15%. Por el tamaño de acuario, posiblemente no pase del 20 o 25%.En mi caso la instale utilizando rieles de aluminio para closet los cuales fueron fijados con tornillos a la base de madera. A los mismos les agregue una mensula a cada uno de las cuales pude colgar la lampara. Lo único que tuve que agregar fueron los candados (dorados) que se ven fijados a las mensuales por que el candado que viene con la lampara esta muy grueso para entrar en el agujero que viene prefabricado en la propia mensula. Incluso utilize el propio riel para esconder el cable de alimentación eléctrica lo cual agrega un toque estético a la instalación (ver 2nda foto).Detalles que podrían ser mejor: En las instrucciones no se aclara cual canal es el azul (Ch 1) y cual el "blanco" (Ch 2) lo cual puede resultar confuso a la hora de programar. Algunos usuarios se quejan de que la intensidad no es ajustable para un efecto de amanecer y atardecer, pero creo que es un detalle menor en relación a lo que cuesta la unidad.En cuanto a la programación, es un poquito confusa pero tampoco nada del otro mundo. Ya se me ha ido la electricidad en un par de ocasiones, apagones muy rápidos y no se ha desprogramado, ignoro cuanto tiempo tiene que pasar para que se desprograme completamente.Espero en los próximos 12 meses adquirir un acuario mas grande y definitivamente una segunda unidad sera una compra segura.Edicion: 2023-07La lampara original empezo a mostrar fallas en la programación luego de 2 años, por lo que la reemplaza con una unidad nueva. Creí que seria exactamente igual pero ya tiene ciertos cambios. De los que son notorios a primera vista:1. La intensidad parece ser diferente. Desafortunadamente no cuento con luxometro. pero a simple vista tuve que dejar la intensidad en 40% para que la misma fuera similar a como la tenia, cuando anteriormente siempre había estado a 18%.2. el ajuste en intensidad anteriormente era de 1 a 100 en incrementos de 1, ahora es en incrementos de 10.3. Anteriormente al inicio del ciclo de encendido. El reloj se encendía mostrando la hora durante todo el periodo en que las luces estuvieran encendidas. Ahora, independientemente de que estén o no encendidas, el reloj no muestra la hora. Por cierto, otro pequeño detalle, antes el reloj marcaba en ciclo de 24 horas, actualmente es en 12 horas con ajuste AM y PM.Por lo demás, puedo reportar que en 2 años de uso de la lampara he estado muy satisfecho con ella. El crecimiento de corales es extraordinario.

I purchased two of these lights to put over my 65g reef. Following advice online I cracked the units open and 'hacked' them to remove all of the lenses except around the outer perimeter to give better spread. (The lenses on the inner side of both fixtures, where they're next to each other, were also removed.) I was impressed to see that there're some decent measures taken to prevent salt creep from invading through the plexi window at the bottom of the light from splashes -- there's both a bead of silicone and a gasket. However, you'll still be out of luck if you drop the thing in the tank.With the bottom of the fixtures about 10" above the surface of the water and the light set at 75/30 I was getting PAR of about 275 mmol about 8 inches down, and about 125-185 on the sand (with the highest levels at the bottom in the middle of the tank where both fixture's coverage overlapped.) With the lenses removed discoballing is reduced and more light reflects back off the sides of the tank internally, giving better light to otherwise shadowed areas. However, the top of my tank is fully enclosed by a hood; keeping the lights this high with no lenses might be intolerable otherwise, if I didn't have something to block the light-spill.The lights are easy to program using the included remote, but a bit of a pain if you want to turn them on during a time when they're set to be off. It would also be nice to have a soft-start that ramps the lights up from 0 over a period of a few seconds, if only to not startle the fish -- but I now have a screen on the top of my tank, so it's not an issue. The whites at 1% are very bright and may provide a tank that's too white for some users even at this level -- however, personally, I found the whites provided at 70/30 to be pleasing.These lights are extremely bright in terms of PAR when put on full, particularly if you keep all the lenses on. The use of a PAR meter to map out the light coverage of your tank is highly recommended when adding these lights to a tank, particularly if your previous lights were on the dimmer side. I have been acclimating my tank to the new light over the past two weeks and am most of the way to where I want to be; coral growth has already taken off compared to my previous, underpowered light.With the way that I mounted my lights, I was easily able to adjust both of them at the same time using a single remote, if some care was taken with the angles. While the onboard clocks can indeed drift apart, it's very simple to adjust the time on the light to get them back into synch.I'm also impressed by their customer service. Through my own ignorance I screwed up one of the hangers; they responded to my inquiry promptly and went above and beyond helping me out.Ultimately, you get what you pay for, but I consider these to be a fantastic value. These are no-frills lights, but they seem to be built decently well and with quality LEDs, and are more than sufficient to grow corals well, and -- though this is completely subjective -- I find their spectrum pleasing. Viparspectra put their money and effort on the things that really count, and pretty much on nothing else.I will likely pull out the LED drivers and replace them with 0-10v versions so that I can use my Apex to dim them, but that's a low priority upgrade. However, given the light's construction, it should be relatively simple to do so.
