PHILIPS CDM Master Color Bulb 315W 4200K LEC

CDM Master Color Bulb 315 W-4200K LEC PHILIPS

The PHILIPS CDM Master Color 315W-4200K LEC bulb belongs to the family of ceramic metal halide ( CMH/LEC ) lamps, known for their broad and natural spectrum. The 4200K (cool white) color temperature provides sufficient blue light for compact leaves, short internodes, and active roots, while maintaining the red light component that accelerates the transition to pre-flowering.

With a true output of 315 W , this light source covers areas of 0.8–1.2 m² with high uniformity when installed in a compatible reflector, generating stable PPFD and colorimetry that facilitates visual tissue diagnosis. The ceramic tube operates at an optimal internal temperature, offering sustained flux and slow degradation of the photon package.

For medium-sized grow tents where the goal is productivity with temperature control, the 315W LEC light reduces radiated heat compared to older technologies while maintaining intensity and penetration. Integrated into hybrid lighting systems with LEDs, it allows for spectrum balancing, increased use of photons, and a more stable microclimate in cannabis cultivation .

At Hydroponics Blanes , a trusted and leading grow shop in Spain , this bulb is recommended for complete vegetative growth, mother plants, advanced rooting, and inspection rooms seeking natural-looking color. Discreet shipping is available throughout the country. It perfectly complements our catalog of LE grow lights designed for efficiency and consistent results.

Indoor Growing Bulb CDM Master Color 315W-4200K LEC PHILIPS

In indoor cultivation , the cool-neutral 4200K spectrum improves photosynthetic rate during the vegetative stage, resulting in healthy leaves and a robust root system. The characteristic penetration of CMH/LEC lighting reaches through dense canopies, equalizes growth across different levels, and promotes a structure suitable for subsequent flowering. Reasonable thermal management helps maintain VPD within target range, even in grow tents with moderate ventilation.

What is the purpose of the PHILIPS CDM Master Color 315W-4200K LEC bulb?

• Fast and compact vegetative growth : short internode, firm stems and intense green color.
• Maintenance of mother plants : stable emission that sustains cutting rate.
• Pre-flowering and transition : balanced spectrum that accelerates bud development without stress.
• Inspection and diagnosis : High CRI that shows true tones to detect deficiencies or excesses.
• Mixed schemes : combination with LED panels to create custom spectral curves in cannabis plants .

Indoor Growing Tool CDM Master Color Bulb 315W-4200K LEC PHILIPS

A professional tool for medium-sized rooms and modular projects. The 315W LEC format provides homogeneous coverage across 0.8–1.2 m² with either an open or closed high-performance reflector. Its blue-peak spectrum limits stretching, defines dense canopies, and improves response to pruning and training. Lower radiant heat compared to older sources helps maintain optimal leaf temperature and relative humidity margins during extended periods.

How do I use the PHILIPS CDM Master Color 315W-4200K LEC bulb?

Electrical compatibility: work only with LEC 315W ballast/driver and specific PGZ18 lamp holder; check labeling before first switch-on.
Mounting: Install on compatible reflector, secure firmly, clean glass with cloth if there was contact with fingers.
Recommended height: 40–60 cm above canopy in vegetative stage; adjust based on PPFD measurement, leaf temperature and green response.
Recommended photoperiod: 18/6 or 20/4 for growth; change to 12/12 when flowering begins.
Climate: gentle cross ventilation, extraction according to volume, recording of VPD and ambient temperature.
Safety: Disconnect power before handling, cool completely before changes, avoid water splashes.
Maintenance: blow dust off reflector, check connectors and hours of use to schedule preventive replacement.
