ZETLIGHT Horizon Shieldo Lamp 144W (Black)

Description

This modern and stylish LED light unit offers maximum customizability, penetration and coverage for the coral reef aquarium.Full Spectrum Lighting with optimal penetration and coverage:
Simulate dawn, sunrise, daytime, sunset and night time by adjusting the brightness and intensity of each color light to simulate the exact spectrum and wavelength you desire.
Total Lumens: 8800 LM (Suitable for coral reef aquariums).
Contain semi ball shaped LED clusters which creates and optical lens effect – greatly improving penetration and coverage of light.
Features a wide spectrum design which greatly enhances coral growth rate.
Contains professionally mixed LED color configurations to suit both shallow and deep water corals.
Specialist moonlight panels simulates the way moonlight diffuses and reflects upon the water surface at night.
Features world class Bridgelux LED’s and chip.
Simulate natural weather conditions such as clouds moving across the sky or lightening storms.
Easily test your installed settings by running demo mode – which will simulate your entire day’s settings in a few minutes.
Unique Design:
Sleek modernist design.
The LED bulbs are housed behind a super transparent toughened glass panel which lets the maximum amount of light through, prevents humidity and is easy to clean.

Running the ZETLIGHT Horizon Shieldo 144W on a reef tank in SG

This is a serious reef fixture, and at 144W it is built for medium to larger coral displays rather than a desktop pico. The lens-style LED clusters push light deep, which helps when you are keeping SPS or demanding LPS lower in the water column. In our warm climate we always flag heat: a high-output light over a reef tank usually pairs with a chiller, so factor that into your electrical and cabinet planning.

The full daylight cycle simulation lets you build a natural dawn-to-dusk programme, and we suggest ramping intensity gradually over several weeks rather than going to full output on day one. Sudden high PAR is a common cause of coral bleaching in fresh setups. Mount it at a sensible height first, then close the gap as colonies acclimate and you read your par across the scape.
