"Commercial High Intensity Discharge (HID) lights use electrodes to conduct power into the gas mixture inside the tubes. Electrode degradation and failure are typically the life-limiting factors for these light sources. With the recent advancement of low cost high-frequency power amplifiers, electrodeless plasma lamps have become a more practical alternative to traditional HID lamps.
Sipp’s APL lamp is a gas discharge lamp energized by radio frequency. It uses high-frequency electromagnetic power to create a plasma in a gas mixture that efficiently produces light that covers the entire spectrum. Different color of the spectrum can also be enhanced based on the use of the metal halide.
During the development of a plant, the requirement of the red to blue light ratio varies. For example, during seeding growth, higher blue component of light is desirable, whereas during germination and flowering, a higher red content can be more desirable. The ratio of red to blue light in Sipp’s APL lamps can be controlled by simply varying the power to the lamp. This allows the same lamp to be used for all stages of plant growth without the need to change lamp types to optimize a particular growth phase.
Sipp’s APL lamps consume less than half the power compared to the traditional High Pressure Sodium (HPS) lamps resulting in less heat dissipation thus reducing HVAC costs. Lower power requirement for lighting and cooling can translate to substantial reduction in operating cost thereby increasing profit."
