Higher Lumen, then higher lux??Higher Lumen, then higher lux??

The measured result of a normal Lux-meter is „photopic lumen“, which is not really corresponding the sensitivity of humen eyes. More scientifically, „scotopic lumen“- pupil lumen (Plm) should be measured for comparasion.

HPS Lamp is 90Plm/W, induction lamp is 140Plm/W

555nm

Normal lamp is point-light or line-light source, efficiency is more reliable from a reflector. Induction lamp is surface-lighting source, which has much bigger luminous surface and better uniformity.

Not definitly!

Induction lamp has 70-90lm/w which is not the higest, however:
