Comparison T5 - HQI

 

Tested were lighting units HQI 2x150W temperature 14.000K (300W) and T5 5x39W (195W). The distance from measured area (60x15cm) was 40cm. Test demonstrates the influence of emitted temperature  by HQI bulbs. By day temperature (6.000K) are results HQI - T5 in the first month very comparable, but by higher temperatures (from 10.000K) the illuminating is in favour of T5 tubes ( P HQI/T5= 300W/195W).
