I bought a HPS light that's (apparently) specific for growing plants indoors. It's a 400W Lucalox PSL T (Photosynthesis light) and on the box it says it is 20% more effective than standard HPS lights. Wot it says on the website is:

A high pressure sodium lamp designed specifically for Horticultural application - PSL: PhotoSynthesis Light
#
Perfect choice for consistent and controlled plant growth
#
230V/400V lamps offer superior PAR (Photosynthetically Active Radiation) output that gives excellent greenhouse light quality
#
Excellent PAR and light output maintenance over the life of the lamp
#
Built with GE's latest Lucaloxâ?˘ XO technology

Wot do peeps think about it? I have fluoros for the 1st few weeks, then wanna switch to ths PSL
