Moon Light (Blue ,Blue and UV)

With the ever increasing number of coral farmers, fraggers, and aquarists with deep aquariums, Orphek has produced the DIF series of LED pendants to satisfy all of these applications without the need for producing multiple models for each application.

Orphek has accomplished this goal by designing four optical quality lenses to fulfill any application, whether they are shallow coral tanks and displays, or aquariums up to six feet in depth.

The available lenses are 45, 60, 90, and 120 degrees and all are made from optical quality glass.

The 45 and 60 degree lenses are suited for deeper aquariums while the 120 degree is better suited for shallow coral displays or fragging systems.

Orphek DIF 100 Lens

The lenses are easily changed simply by removing the threaded lens housing and replacing the lens.

The DIF housing is constructed of high grade aluminum and employs an extruded aluminum heat sink which wraps around the entire housing and efficiently cools the unit without the need for noisy fans.

The use of Mean Well high efficiency LED drivers in the DIF series LED pendants ensure constant voltage and current to within 0.5% and provide over current protection to the LEDs.

Orphek uses extruded aluminum for the DIF series heat sinks.

Extruded aluminum is more expensive than die cast but ensures even heat dissipation because unlike die

cast, no porosity exists in extruded aluminum which can impede heat transfer.

Revolutionary, Powerful, Efficient, Versatile, Durable

The Orphek R&D team developed a revolutionary emitter with a new Two-in-One technology for use in the DIF series of LED pendants.  This technology mimics the ripple of metal halide lighting and also mimics  16,000K ,18,000K 20,000K, 25000K lamps without the use of low lumen blue LEDs which other manufacturers use to obtain this effect

Orphek offers you a selection of color temperatures which include 16,000K, 18,000K, 20,000K, and 25,000K  White LED.  With these Kelvin temperatures, no additional blue LED  lighting is required.

The Orphek Team has designed the DIF series LED pendants offering three different power options.

DIF100 – 100 watts

Two model options are available; the DIF, and the DIF-XP. 

The DIF-100  XP  offers safe high range (380nm) UV, and red LEDs to provide better fluorescing and improved color for your corals.

The spectrum of the XP model is very similar to that of the Radium 400 watt, 20,000K metal halide lamp.
