    To illuminate a reef tank, there are many options in terms of type of lighting and different brands for each type. Maybe we should start with why do we want to keep a reef system? For me, it was the coloration and reproduction of zoanthids and mushrooms over 25 years ago. For most, the most fascinating aspect of keeping a reef system is to bring a small piece of nature into our surrounding, whether that is our living room or a fully equipped fish room/basement/garage. Over the years, reefers and various brands of LED lighting have proven that LED lighting can sustain the most demanding corals such as SPS. The benefits of using LED as the primary lighting have outweighed other types of lighting such as T5’s and metal halides (MH) with power consumption, heat and general running costs. Until now, none of these artificial lights for reef system were able to mimic the sun’s travel right out of the box and this is the reason FOCUSTRONIC LED’s were created. In some extreme cases, DIY reefers may consider building their own light moving rails for MH but there is significant amount of construction over the top of the reef tank in order to get a system going. We will look at 3 main areas when selecting a lighting system for a reef tank.

    First and probably the most important is the lighting output (PAR) you get from your fixture. There is a negative correlation with all lights and that is the higher it is mounted, the wider the spread but also the less PAR received by the corals. With a FOCUS 1, at 12” above, FOCUSTRONIC is able to get well over 1100 PAR with a MQ-500 PAR meter which is one of the most common PAR meters among hobbyists (before adding the 32% they Apogee suggested). In many articles, the optimal PAR for corals in general is around 250-300 PAR. With FOCUS 1 pumping out over 1000 PAR at 12”, FOCUSTRONIC can easily cover a large area when mounted at the suggested height of 8-12” above water depending on the depth of your tank. One of the biggest drawbacks with LED lighting is shadowing and hot spots since LED’s output is a very focused beam of light in order to penetrate into the deeper parts of the tank. FOCUS 1 is able to provide a very good solution to both of these problems with a dynamic LED light source by rotating the head that houses the LED cluster at each hour by 4 degrees. By default, the angle is changed every hour with 12:00 (noon) being facing directly down just like the sun being at zenith position. The user has full control on the movement of the angle so that over the hours of max output, the fixture is able to provide multiple sweet spots without the risk of burning coral. One common misunderstanding of the rotating angle is that it will cause uneven light spread during the sun rise and sun sent hours. The angle rotation actually offers 2 main benefits which makes the tank more naturally looking and providing light from different angles. For users that like to view their tank with an even spread of light, they can simply adjust the angles of the hours which they are likely home viewing the tank to be around 0 degrees or just slightly tilted so that the light will be more evenly spread. On the other hand, if the user is likely to view the tank for longer hours, they may want to have a more natural looking reef based on a sun rise and sunset schedule so that it is brighter at one side during sunrise and vice versa. With a rotating light source, the sunrise and sunset will be much more natural and not just turning on or off from either ends. Shadowing is another common problem with reef tanks due to design of the aquascape and also coral colonies growing too big and shadowing anything below them. The only way to solve this is to direct the light to the shadowed areas from an angle so that light is not blocked from the top. With this ability, FOCUS 1 can grow more corals in area where lights with only a top down direction won’t be able to penetrate. Last but not least, the full spectrum with the FOCUS 1 is perfect for the reef aquarium and inhabitants with 4 UV LEDs at 410-420nm. The unit is rated at 114 watt maximum output with 7 independently controllable channels of cool white, warm white, red, green, royal blue, blue, and UVs.

    App Interface & Features:

    The FOCUS 1 is packed with features you can expect from similar high end LED fixture but of course with the dynamic light source which no other reef lighting can offer. Apart from the default profiles, the user can create their own profiles with the Profile Wizard and Profile Composer. With the profile wizard, the user simply sets a start hour and end hour with 3 time points of light intensity for the 7 LED channels. Once the profile is generated, the user can easily add or delete a time point on the schedule by tapping the line of the hour or long press to delete. The profile composer is for advanced users which can adjust each hour of the schedule to make fine adjustments. FOCUSTRONIC suggests first time users to start with the Profile Wizard to construct the basic profile and try it for several days to see the overall effect. Once all the major adjustments are done, you can convert the profile to the expert format which opens up all the features like setting angles for each hour based on the light requirement of your tank and corals. One of the unique features I like with the App is we can have different time offset for weekends. This is especially useful because many of us will need to leave our house for work during the major part of the day and back in the late afternoon except the weekends. We can adjust the offset so that we can view the part of the schedule while we are most likely home and let the light do all the rotation during the hours we are away. This always allow you to view your tank with the best lighting effect while you are home. The App also includes a moon light which also mimics the moon cycle based on the lighting intensity you have set. In one of David Saxby’s article, he suggested that corals will do better with a varied intensity and this can be achieved with the weather features of the App. There are 4 weather settings that can used and will be activated randomly in enabled time point.


    The last point I would like to discuss will be connectivity. With all the features of the FOCUS 1, there is no easy way you can use onboard buttons to setup the light. Wireless connection is the only sensible way because even with a USB cable, it could be quite fiddly. The best part is that the wifi connection is built in and do not require additional equipment or a home router. Unlike some other brands, each unit is capable of being the master and/or slave.

    FOCUS 1 opens up a whole new chapter for reef lighting. It offers something we as a hobbyist could only dream of until FOCUSTRONIC comes along. The product is built with exceptional quality and the highest grade of materials are being used. There is no doubt that the FOCUS 1 will be able to grow the most demanding corals but only how much better than static light source LED fixture. With the current MSRP, hobbyists can feel comfortable trying this new light which offers a dynamic light source to enhance natural coral growth.

    As you can see in the photos, I am able to light 8’ x 4’ tanks with only four FOCUS 1 lights over each tank. If I were to use comparable static LED’s I would have to double the amount of fixtures to achieve the light output that’s required to light such large tanks. The possibilities, settings and features of the FOCUS 1 are truly endless.

    I would like to add that the FOCUS 1 will fit on a Radion mount, an Aqua Illumination mount and a Giesemann mount. The Giesemann mount will require an adaptor plate.

    Very nice write-up and I am looking forward to trying these. One question I always have with different brands of LED, how does the color rendering of corals stacked up with other LEDs out on the market?

    Thanks! The colors are awesome. You have the ability to customize to the exact color that you're looking for. All light channels are adjustable individually.
