How to program our Photon fixtures
Q: Can you make a recommendation for lighting my tank?
A: Sure, click Here to download a table of fixtures vs tank dimensions and gallons. If your tank is not in the table, you can email us through the contact for a recommendation.
Q: How should I program my light?
A: Typically we recommend starting out at around 30% max on all channels, and adding about 10% a week to acclimate your corals to the new light. Click Here to download the instructions, and click Here to download a program that will recommend a 12 hour program based on a starting time and maximum intensity.
There is not one program that will work for everyone, we cannot give you an exact program to use. Set the light to your color preference, then start out at a lower power and gradually add to that. Most users stop adding intensity at around 70% power.
Q: Can I use glass tops on my tank with LEDs?
A: Of course! As long as you keep the glass clean, it should not be an issue. Like your current, or any lights, the glass top may block some light. As long as it is free from salt crust and condensation it should not become an issue.
Q: What does the 2 year USA warranty include?
A: Our 2 year warranty includes parts, labor, and shipping both ways, for any fixtures broken due to workmanship errors, burnt out LEDs, broken controllers, and other damage not caused by misuse or faulty hanging. It does not include damage incurred by the user, water damage, or damage caused by power surges, or poor ventilation (i.e. a closed canopy with no fans). The customer can either have us repair the units, or repair it themselves with parts that we provide.
Q: How do I change out LEDs?
A: For the SuperLux and Original Photons (the V2s use Cree LEDs, which cannot be soldered by hand) it is a fairly simple process, you need a soldering iron (70watt pencil tip works best), solder (1mm lead solder), thermal grease (not thermal paste, thermal paste hardens when cured, grease does not), and tweezers or small needle nose pliers.
First, you melt the solder on one side of the LED you wish to change, and pull the LED up gently by the base. Then, you de-solder the other side of the diode, and remove it with the tweezers. Add a dab of thermal grease to the center pad to ensure good thermal contact. Then take the new diode, orient it correctly (the negative side will be denoted by a small – sign) and solder it down to the board, one side at a time.
Be sure to apply gentle pressure to the diode when the solder is liquid, so that the thermal pad beneath the LED makes physical contact with the board. Please be sure to only use 3watt bridgelux/epistar LEDs, 1watt LEDs will not work with our lights. The forward voltage should be about 2.5-3.2V, and the maximum amperage should be 700ma.
Q: How do you change out the optics, and what is the difference between 60s, 90s, and 120s?
A: You can simply unscrew the case of the fixture with a phillips tip screw driver, and then flip the top of the case forward (the controller side on the photon units, the side opposite the dimming knobs on the value series). You can then unscrew the board, and flip the board forward as well, which will allow you access to the optics, and LEDs. You can simply pull the old optics off, and put new optics of your choice on in their place, they snap right in. Put the board back, and tighten the screws until they are snug.
The 60 degree optics will have a lot of depth penetration, but not a lot of spread, and are ideal for 30″- 40″ deep tanks. The 90s have a decent amount of depth penetration, but more spread than the 60s. We recommend them on tanks from 18″ deep, to 30″ deep. The 120s (or no optics on the value fixtures) have a lot of spread, but not too much depth penetration. They will work on tanks up to 24″ deep.
Q: How high should I mount the light off of the water?
A: For tanks 12″ front to back or less, 6″ is plenty of height. For tanks 12″ to 18″ wide, 6″-10″ is a good height. For tanks 18″-24″ wide, 8″-12″ is a good height. We do not recommend a single light for more than 24″ of width front to back.
Q: Can any of the Reef Breeders LED fixtures be controlled by an Apex or Reef Keeper controller?
A: No, they cannot be controlled with 0-10v or PWM dimming.
Q: Can I change out optics or LEDs without voiding the warranty?
A: Yes, you can. So long as the fixture is not damaged by your modifications, the warranty policy is still good.
Q: What is the distance between the hanging screws/hooks on top of the fixtures?
A: From left to right:
Photon16: 8 1/2″ between the mounting screws
Photon24:12 3/4″ between the mounting screws
Photon32: 21 1/4″ between the mounting screws
Inner hanging set: 17 and 7/16″ between the mounting screws
Outer hanging Set: 35 and 5/8″ between the mounting screws
Value Fixture: 8″ between the mounting screws
From front to back, the distance is 5 7/16″ on center.
Q: Do you ship internationally?
A: Yes, we ship world-wide. Shipping to Canada, Australia, and France is a flat $50. Please contact us for a shipping quote if you are not located in those countries before you order. Include in your email the light you would like to order and your full address.
Q: Which service do you use for shipping?
A: We ship via FedEx home delivery from Shelton, CT. It takes about 5 days to get to the west coast, and about 1-3 days for the rest of the continental US.
