The Philips MASTERColour CDM-T Elite 315W/942 produces a natural white 4200K spectrum that closely resembles daylight. This allows plants to develop a compact structure, healthy leaf growth, and natural color development.

Thanks to its broad full-spectrum, this CMH lamp is suitable for the entire grow cycle, although the 4200K version is particularly valued during the vegetative phase and for mother plants.

Suitable for

• Vegetative phase
• Full grow cycle
• Mother plants
• Cuttings
• Grow tents
• Grow cabinets

Recommended settings

CMH lamps produce less radiant heat than HPS, but still require adequate ventilation.

Vegetative phase

• 45–60 cm above the canopy

Full cycle

• 35–50 cm above the canopy

Regularly check the leaf temperature and adjust the distance if necessary.

Natural daylight spectrum

The 4200K color temperature provides a bright white light with a broad spectrum. This allows plants to develop sturdy stems, short internodes, and a healthy leaf structure.

High color rendering

With a CRI of 93, colors are rendered naturally. This makes the lamp not only suitable for plant growth, but also for an accurate assessment of the health and development of the crop.

When to replace?

The lamp has a technical lifespan of up to approximately 30,000 operating hours. For optimal performance, many professional growers recommend replacing the lamp preventively after approximately 15,000 to 20,000 operating hours, so that light quality and light output remain maximal.
