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

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

I've had a pair of 165w Viparspectras over my 60 gallon tall mixed reef aquarium for two years, and could not be happier.If you like the idea of a pronounced shimmer effect, wifi settings, ramping up/down, sure this light doesn't do any of it, and the item description says it outright.More importantly, if you want a light that will produce spectrum and par levels that allow you to grow soft coral, LPS coral, and YES SPS coral, this light is up to it, and you can see examples of all in my aquarium.An awesome entry level light that doesn't need to be replaced or upscaled for different coral.A great light when you just want it to work, and save you a little $ to spend on bigger coral.

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.

Only had these a few days. Replacing a AquaLife 72" T5 set up which ran well for about 12 years but finally died.Positives:* Easy to mount from the ceiling.* Seems well built* The lights are more "shimmery" than the T5s* Fairly easy to set up* The blue channel is a much deeper blue than the T5s* My old 5T fixture cost about $180 to replace the 8 bulbs each year and this LED is more energy efficient.Negatives:* Not loud but much louder then my old Aqualife which had a total of two fans. This pair has 6 fans. Not bad but my tank is in the same room as my high end music listening room.* No night light. My old fixture had 6 small blue LEDs for a nice night light. I pulled them out of the old fixture and mounted them in my hood on a timer. Would be nice to have a built in night light as a third channel.* Does not seem be a way to just turn on channel one or channel two without setting it up in the timer. When you adjust the brightness both channels come on at the set brightness.* One of my remotes came broken. I only needed one but was able to super glue the broken one to repair the cracked plastic. I didn't ask the seller for a replacement, it was easy for me to fix it.Overall happy so far. I set the dimmer down to 15% for the first 3 days and then up to 25% so the coral can adjust to the LED light. I had no light for 4 days but nothing died. Many of the mushrooms lost color but its already coming back strong. I am going to keep ramping up the dimmer every week.

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.

This light is great! Have been using it on a reef tank for about 2 months now and can't say a bad thing about it. Corals are growing both sps and lps. The timer feature is great, maybe not as advanced as some may want but you can set different times for the 2 different channels (blue and white) and also set the brightness for each channel. it comes with hanging wires also. Overall can't go wrong for the price.

I have the light set up with my own temporary hanging setup over my 45 gallon reef tank now and it looks fantastic, but I can't for the life of me figure out the timer, the instructions are pretty straight forward but both channels seem to be on the same spectrum of white and not blue? And also I'm missing the hanging set which was supposed to be included and I have no idea how to go about getting a replacement?! I'm giving the product a 4 star because the light is good and it is very bright but the problems with the timer and the missing hanging equipment is very frustrating...
