� Lamp burning hours

� Voltage, Current, Ballast Temperature, etc. �

Consumed energy (calculated)

� Standard Protocol for Communication -Utilizes ISO 14908-2 global standard - Bi-directional real-time communication

23

Most Common Types of Lamp

� Mercury Vapor - Very common- Being replaced because of poor energy

efficiency

� HPS and MH - Second most efficient and are - Currently being used to replace MV lamps -Standard for traditional new installations and replacements - Poor CRI

� LPS - Most efficient- Very poor color rendering

� LED - Great CRI - Higher life span -Decreasing costs -Improving efficiency -Improving lenses/optics - More favourable power reduction normative

24

Lamp Replacement Strategy

� Typically mercury vapor lamps are used for street lighting and other outdoor lighting (car parks, etc)

� Lamps are bring replaced with energy efficient lamp High Intensity Discharge (HID) as follows: - For Street Lighting

� High Pressure Sodium - 200 to 400 W (Orange-White color Light)

- For Warehouses, Outdoor & Parking Lots � Metal Halides - 100 to 250 W (Natural White color Light)

- Some cities (e.g. San Jose, CA) use � For Street Lights

- Low Pressure Sodium - 180 W (Yellow Light)

25

EkoLum Segment Gateway simplifies Installation

� Main challenge- Installation needs to be done by electricians with no LonWorks

skills

- Many devices of the same type (e.g. lamps) need to be installedon the correct location

- Changing damaged devices needs to be simple - System functionality and reliability needs to be checked easily and fast

Installation time is money!
