Description

Arcadia Natural Sunlight Full Spectrum Fluorescent Tube 18W 24" (FSU18)

The Arcadia Natural Sunlight Tube is a full spectrum fluorescent lamp designed to simulate, as closely as possible, the spectrum of natural sunlight in both the UV and visible colour regions — making it one of the most natural and versatile aquarium and terrarium lighting tubes available.

Designed to give a warm natural balance and excellent colour rendition, the Arcadia Natural Sunlight delivers high light output at a colour temperature close to that of natural sunlight at 5,600K. The result is beautifully natural illumination that brings out the true colours of fish, corals, plants, reptiles, and their environment — exactly as they would appear in natural daylight.

Key Features

Full spectrum natural sunlight simulation: Designed to simulate the spectrum of natural sunlight including UVA and low levels of UVB — as close to real sunlight as fluorescent technology allows
5,600K colour temperature: Warm, natural daylight tone that delivers excellent colour rendition for fish, plants, corals, and reptiles
High light output: Delivers strong, consistent illumination across the full spectrum
18W / 24 inch: T8 fluorescent tube — fits standard 24-inch T8 aquarium and terrarium light fittings
12-month lifespan: Long service life — replace annually to maintain full spectrum output and natural colour rendition
Made in Germany: Arcadia's trademark precision engineering and quality control
Versatile: Suitable for freshwater aquariums, planted tanks, terrariums, and vivariums — anywhere a natural full spectrum light source is required
Produces excellent natural colours: Enhances the natural colouration of aquatic and reptile life under a realistic daylight spectrum

Replacement interval

Replace every 12 months — even if the lamp remains visibly lit, UV output and spectral quality degrade over time. Annual replacement maintains the full natural sunlight spectrum for which this lamp is designed.
