I need the spectrum (image), as well as lumens and colour temperature specifications, of the following lamps from Philips: TLK/40W (which is an UV lamp), Cool White 18W/840 and the Master TL-D Super 80 18W/827. I have tried a crazy lot of searches with poor results. Or ideas on what lamps to use, beside HID- an HPS lamps, would also help. It’s for sustaining some Southern African trees (Acacia) indoors.
