Build My LED 12000K REEF SPECTRUM - XB SERIES with Black Finish
A brilliant white LED fixture that will show off the natural colors of your fish and corals...
This is the Very High Output version of our already powerful 12000K Reef Spectrum fixture. The 12000K Reef Spectrum XB Series delivers 31% more light than their original 12000K Reef Spectrum. The XB Series uses the same amount of electricity and contains the same LED colors that are used in the original series.
Build My LED calibrated the commercial-grade LEDs in this fixture to produce a bright, white light similar to what you would see at noon in an equatorial reef. This spectrum emits the wavelengths needed by the Zooxanthellae algae which produce food needed for the survival and growth of most hard and soft corals. The fixture’s accurate color rendering capabilities will reveal the natural colors of your fish and corals as they would appear in bright sunlight. It produces approximately the same high power (PAR) readings per linear foot as their 14000K Spectrum Light. Use in conjunction with the Super Actinic for maximum coral fluorescence.
Recommended for: Reef keepers who desire a white, natural color in their reef aquarium. Does not produce strong blue tones associated with most reef LED lights.
- LED Selections per 12" Board: (7) 6500K Cool White, (4) 450nm Royal Blue, (2) 470nm Blue, (1) 525nm Green, (1) 660nm Deep Red
- Build My LED purchases top-bin LEDs from the world's largest and most reputable LED manufacturers (i.e. Philips Lumileds, Everlight, etc.).
- We use 1W and 3W LEDs in our fixtures, and they are driven at 350mA to ensure long life and high electrical efficiency. Due to the large number of LEDs we use in every fixture, we do not need to overdrive the LEDs to achieve extremely high PAR ratings.
- Product Features: 0-10V Dimmable Driver (Dimmable from 100% to 10%). Compatible with these controllers: Apex, Reef Keeper Lite and Reef Angel - IP66 Waterproof Rating- CE Safety Certification & ROHS Compliant- Built-to-Order in the USA- 3 Year Warranty- Innovative 'T-Rail' for Unlimited Mounting Options- Return within 30 Days for Full Product Refund- System Includes: LED fixture/power supply/8' cord/plug/mounting brackets.
PAR (Photosynthetically Active Radiation) defines the type of light that is needed by corals (specifically, coral’s symbiotic algae) for photosynthesis and it is measured in micromoles per square meter per second (μmol/m2/s). PPFD (Photosynthetic Photon Flux Density) is a measurement of the amount of PAR that falls on a given area every second, and it is an extremely important metric for successfully propagating corals in your aquarium. All of our LED fixtures emit extremely high PPFD levels -- far higher than any fixture in our price range.
You need to define a desired light level to calculate the number of fixtures needed on your tank. Use these definitions as a guide:
Ultra High Light is defined as the light level that should only be used by advanced aquarists and researchers seeking to maximize coral coloration through elevated chromoprotein levels. Ultra high light will usually require the use of multiple fixtures, and users should have experience in maintaining a reef aquarium under high PAR levels. Depending on the light levels the corals were previously exposed to, users should slowly acclimate their tank to this light level by using a manual dimmer or a controller.
High Light is defined as the light level you will need to successfully grow hard corals, including SPS. This will likely require the use of multiple fixtures. Depending on the light levels the corals were previously exposed to, users should slowly acclimate their tank to this light level by using a manual dimmer or a controller.
Medium Light is defined as the level that is most often used to successfully keep soft corals and LPS in your aquarium. In the event only one fixture is required and you want to add a supplemental fixture (Pure UV, Purple Wave or Super Actinic Reef), the use of a manual dimmer or controller is recommended to lower the total light level.
Viewing Light is used by those who don’t intend to grow coral but want an illuminated tank where the colors on fish will stand out.
IMPORTANT NOTE: The fixture calculator is designed to give you a recommendation on the number and length of fixtures needed to achieve a specified light requirement in the tank you select. Due to rounding, the calculator may return the same recommendation for multiple light levels. This is not an error.
To achieve the highest light (PAR) levels in a reef aquarium with a single fixture (or single row of fixtures), we recommend the 75 or 90 degree beam angle mounted 2-3” above the water. Select the 75 degree beam angle on tanks measuring up to 12” wide (from front to back) and a 90 degree beam for tank widths over 12”.
When mounting at this height (2-3” above water line) the 60, 45 and 30 degree beam angles should only be used on aquariums with multiple rows of lights or to “target” a particular area. This level of light is usually only required in when you are trying to target specific areas of the aquarium (i.e. clams, island reefs, etc.).
Once you know your fixture mounting height, use the following as guidelines for determining the proper beam angle to use:
Height Above Water:
- 2-3": 90 degree beam angle
- 6-11": 75 degree beam angle
- 12-23": 60 degree beam angle
- 18-24": 45 degree beam angle
- >24": 30 degree beam angle
