Development of compact floodlights using 2kW short arc metal halide lamps

Photokeratitis and UV-radiation burns associated with damaged metal halide lamps.

BACKGROUND Damaged metal halide lamps are known to cause outbreaks of photokeratitis and UV-radiation burns among children and adults, which has prompted the Food and Drug Administration, Rockville, Md, to publish consumer recommendations to prevent such injuries. We investigated 3 outbreaks of photokeratitis and UV-radiation burns in gymnasiums associated with failure to heed these recommendat...

Climate Technology & Development Case study: Compact Fluorescent Lamps (CFLs)

VIPower: SELF–OSCILLATING CONVERTER USING VK05CFL FOR COMPACT FLUORESCENT LAMPS

This application note introduces a new self–oscillating converter based on VK05CFL device to drive “SE”, “DE”, and “TE” fluorescent tubes. The design is intended for 5 to 23W fluorescent lamps and 110V, 230V ± 20% main voltage.

Vegetative Growth of Potato under High- pressure Sodium, High-pressure Sodium SON-Agro, and Metal Halide Lamps

Potato (Solanum tuberosum L. cvs. Norland and Denali) plants were grown under high-pressure sodium (HPS), metal halide (MH), and blue-light-enhanced SON-Agro high-pressure sodium (HPS-S) lamps to study the effects of lamp spectral quality on vegetative growth. All plants were initiated from in vitro nodal cultures and grown hydroponically for 35 days at 300 μmol•m–2•s–1 photosynthetic photon fl...
