T&K Lighting (T&K LMS) Management System is suitable for indoor and outdoor lighting. It is compatible with a wide variety of lamps, such as high and low pressure sodium, mercury vapour high pressure, fluorescent low pressure lamps and compact fluorescent lamps. The maximum achievable power saving of each lamp type with our system is tabulated below:
Lamp Type |
Power Saving [%] |
| Fluorescent lamps with magnetic ballasts |
18% - 25% |
| Fluorescent lamps with electronic ballasts |
15% |
| Mercury vapor high pressure lamps |
30% |
| Energy saving lamps (low power) |
18% - 30% |
| Metal halide lamps |
30% |
| High-pressure sodium lamps |
40% |
T&K LMS is the leading product in the market with its patented technology. There is no existing technology that has the same features of energy saving, reduction of electronic waste and smooth dimming performance in the market.
Competition Using Other Technologies:
T&K LMS vs. Transformer
Transformers have been used in the lighting market for energy saving. However, they are inferior to T&K LMS in terms of performance, cost and flexibility as shown in the following table:
