Higher Lumen, then higher lux??
Not definitly!
Induction lamp has 70-90lm/w which is not the higest, however:
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.
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
