Tungsram

Tungsram XO lamps combine long life and excellent luminous efficacy to deliver low operating costs and energy efficient performance.

Plants require certain radiation levels to help with photosynthesis. The Tungsram PhotoSynthesis Lamp (PSL) has been specially developed to provide stable lumen maintenance and increased Photosynthetically Active Radiation (PAR).

Measured in micromole/sec, the increased PAR output of this lamp simulates natural daylight to maintain plant growth under artificial lighting conditions.
