GRENLite™ s vs. LED

Comparison Item

 

GRENLite™

 

LED

Market Potential Size

 

GRENLite™ 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 energy-saving light sources development.

 

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.

Economy

 

With the development of large-scale production, GRENLite™ cost will be reduced much.

 

The higher cost of LED will be kept for many years, so its wide application will be limited.

Energy Saving Applications

 

GRENLite™ can save up to 50% of energy consumption than LED, because GRENLite™ efficacy is 30% higher than LED and lumen depreciation rate is lower much than LED.

Can be used in the industrial, commercial, roads, tunnels, bridges, gardens and parks, agricultural, advertising lighting

 

LED will consume much more energy than LVD lamps because of its lower efficacy, higher lumen depreciation rate.

Can be used in the traffic signal, vehicle rear lights, LCD panel back-lighting, display lighting.

Functional Lighting Applications

 

GRENLite™ can be widely applied for diversified functional lighting application. It is commercialized quickly around the world

 

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.
