The Narva NC-DE 70W 20000K is a high-output double-ended metal halide lamp designed specifically for deep marine and reef aquariums. Operating at 70W with a color temperature of 20,000K, it delivers a crisp, bright, blue-white light that closely replicates the intense solar conditions and visual clarity of natural saltwater environments.
Key features and details include:
- Ideal Spectrum for Corals: The 20,000K spectrum provides the deep blue-white wavelengths essential for the health of both soft and hard corals, while causing marine life to fluoresce beautifully.
- Design & Build: Built as a double-ended (R7S base) round glass tube, it is engineered for resilience against the high-moisture and corrosive conditions typical of marine setups.
- Illumination: Delivers potent, localized flood-lighting, allowing it to penetrate deep into large marine aquariums.
- Maintenance: Offers robust longevity. However, to maintain optimal spectral emission and tank clarity, hobbyists typically replace the bulb annually or when noticeable dimming occurs.
- Availability: Widely available from specialized aquarium suppliers, often retailing for approximately 3,200 per piece.
