Description

Lumatek CMH Lamp 315W 4200K – daylight spectrum for vigorous growth

The 315 W CMH lamp (Ceramic Metal Halide) from Lumatek provides a balanced 4200 K daylight spectrum with very high color rendering (CRI > 94) and strong photosynthetically active radiation – ideal for the vegetative stage, mother plants, and as a full-spectrum supplement. Typical values for the 4200 K version: PPF approx. 615 µmol/s, luminous flux approx. 38,000 lm, service life up to 14,000 h.

The lamp is a pulse-start type, designed specifically for electronic 315 W CMH ballasts with low-frequency square-wave output. The PCA ceramic arc tube ensures stable operation, high efficiency, and consistent spectral quality; the CRI > 90 underlines its sun-like spectrum. Available in 4200 K (Daylight) and 3100 K (Agro).
