Orphek will offer their new DIF LED pendants in the following configurations:
Wattage: 100 watts, 50 watts, and 30 watts (DIF-100, DIF-50, DIF-30)
Lens: 120 degree, 90 degree and 60 degree
Spectrum: 25000K white, 18000K white, 15000K white, 10000K white, 420-480nm blue, and 580-660nm red. Custom spectrum are available for high-volume orders.
The interchangeable optics is a novel concept. The photo (right) shows a close-up of the dome-shaped lens which users can customize, switching between 60 degree, 90 degree, or 120 degree lenses in order to focus light to best suit their system. For example, the 60 degree lens will help penetrate deeper aquariums while the 120 degree lens will work better for shallow tanks.
Orphek claims light output up to 90 lumens per watt, making these lights the most efficient single die LED available in the hobby. The 100 watt version will output light equivalent to a 400 watt metal halide. The 50W version is comparable to a 250W metal halide, and the 30W version is comparable to a 150W metal halide.
The all-metal fixture is coated with a corrosion resistant coating. In conjunction with constant-current electronics, these pendants are designed to withstand humid or salty environments. The DIF pendants are all-in-one stand-alone fixtures, meaning no external ballasts or electronics are required. The light is also passively cooled to provide totally silent operation.
The Orphek DIF pendants are UL listed, CE, and ROHS certified.
