The D-D Spektrum LED Light has been designed specifically for reef aquariums, combining powerful output with a balanced spectrum to deliver exceptional coral growth, vivid colouration and fluorescence. With two variants — the Spektrum 90 and Spektrum 150 — this range offers solutions for both smaller and larger reef tanks.
Both models feature a carefully engineered mix of Cree and Lumileds diodes, producing a clean blue spectrum with added whites, violets and UV channels to stimulate photosynthesis and bring out natural coral fluorescence. Wide-angle blending optics ensure even coverage without glare, while the recessed lens design enhances light distribution.
Cooling is managed via a solid aluminium heatsink and thermostatically controlled fan, ensuring reliable operation and long service life. The unit is splash resistant, with conformal-coated electronics for added protection.
Control is simple and flexible through the D-D Spektrum app, which allows full wireless access via Wi-Fi or local connection. Users can create custom schedules with sunrise and sunset effects, set lunar cycles, use acclimation modes, group multiple lights together, and share presets with other aquarists.
Mounting options are versatile, with compatibility for HTMG2, OTM Rails, HMS Single Arm and an optional hanging kit. Whether you choose the compact Spektrum 90 for aquariums up to 60 × 60 cm, or the larger Spektrum 150 for systems up to 80 × 80 cm and demanding SPS corals, you’ll get consistent PAR output, energy efficiency, and an elegant, modern design.
