Philips Alto Ceramalux HPS Bulb

Description

Plant growth (photosynthesis) is not then determined by lux or energy, but by the photons from the blue to red (400–700 nm) part of the spectrum. This is called growth light! For horticulture, natural daylight (global radiation) is in most cases measured in terms of energy (J or W) with a solar meter.

Features:

• clear tubular outer bulb
• high output
• long reliable lifetime
• orange/red spectrum (best for flowering plants)

The value of global radiation is important for climate and humidity control in the greenhouse. Extremely high quality sodium bulbs that produce more lumens than standard models and last much better than the competition.
