What spectrum and strength of light are best suited for indoor tomato and pepper growing? I have around 2,5m2 of surface. The room walls will be coated with mylar.

If you can be product specific, that would be great, since I find commercial descriptions rather confusing. For example: light product here. This light is 300W, but lower in the description is stated that it consumes only 132watt±10%.

Apparently it generates 2.5 more energy than it consumes :))

Other manufactures describe lamps in a similar way.

Thanks for help.

The important factors are the light spectrum and the lumens , not the watts. I have found more information for aquarium light products than garden lights . A metal halide ( not halogen ) with a 5000 C temperature rating would be good but use a lot of power ; available in wattage from 150 to 500 and maybe more.
