Higher Lumen, then higher lux??
Normal lamp is point-light or line-light source, efficiency is
more reliable from a reflector. Induction lamp is surfacelighting
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
Not definitly!
Induction lamp has 70-90lm/w which is not the higest, however:
555nm

Energy saving
Induction lamps can replace most of conventional light
sources in functional lighting fields, so its potential
market size will be huge. In addition, the incandescent
lamp will be phased out in many countries in the very
near future, so there will be a big space for energysaving
light sources development.
With the development of large-scale production,
Induction lamps’ cost will be reduced much.
Induction lamps can save up to 50% of energy
consumption than LED, because Induction lamps’
efficacy is 30% higher than LED and lumen
depreciation rate is lower much than LED.
Although LED has many years of history, it only can be
used for the traffic signal, vehicle rear lights, LCD panel
back-lighting, display lighting because of lower lumen
efficacy, lower wattage, and less lighting fixtures
accommodated. It will take a lot of time to develop large
wattage model of LED in order to apply LED in the
functional lighting fields.
The higher cost of LED will be kept for many years, so its
wide application will be limited.
LED will consume much more energy than Induction lamps
because of its lower efficacy, higher lumen depreciation
rate.

advertising lighting.
Induction Lamps can be widely applied
for diversified functional lighting
application. It is commercialized quickly
around the world.
1. Wattage:15W~400W
2. Efficacy:>80 lm/W
3. CRI:>80 Ra
4. CCT:2100K~6500K, All range.
5. Lumen depreciation:5%@2000hrs
6. Lifetime:>100,000 hrs
7. Heat output:much lower
8. Fixture accommodated easily
9. Linear light source:no glaring and
flickering, better light quality.
LED
Can be used in the traffic signal, vehicle rear lights,
LCD panel back-lighting, display lighting.
Because of lots of barriers for LED’s R&D, it will
take 5~10 years for LED to be applied widely in the
functional lighting application.
1. Wattage:0.5~50W per each. Big wattage output
needs hundreds of LEDs。
2. Efficacy :80 Ra
4. CCT:narrow range(white LED)
5. Lumen depreciation :>50%@2000hrs
