Luminaire complies with the requirements of CE, CISPR 15 Ed 7.2, IEC 61347-2-13, IEC 61547, IEC 62384.

GreenBay is an integral LED luminaire with a pressure die cast housing with dedicated optics for optimal light distribution. A specially designed heat management system to ensure luminous efficacy > 80 lm/ W for the system and ensure lumen depreciation upto 30% over 50k burning hours. The luminaire is designed to meet IP 65 classification and is compliant with relevant immunity, safety and performance and EMI standards.

Why GreenBay?

Instant Start

HID lamps especially metal halides require upto 6-8 minutes to restrike after a power outage. To address this temporary blackness, customers tend to use additional emergency lighting systems.

GreenBay with its LED technology is always instantly ON when power is fed to the system.


Within industrial sheds, the temperature within the premises tend to be higher than the outside ambient temperature. LED solutions are vulnerable to high temperatures with an adverse effect on the light output and the useful life. GreenBay LED luminaire is designed to meet its specifications on performance & lifetime at a design ambient of 45 deg C.


In an age of shrinking natural resources & power capacity deficits, energy saving is a desirable scenario in most applications. The challenge is to maintain the current levels of lighting performance & still offer significant energy savings. GreenBay LED lumunaires are designed to save minimum 40% energy saving without compromising on lighting performance.

Low on maintenance

In Industrial applications, it is important to provide a solution that can withstand the industrial conditions without the need for frequent maintenance. In such a scenario, it is important to ensure that all constituent components are designed to function optimally in conjunction with one another to achieve the best possible lifetime. GreenBay is an integrally developed solution that ensures the lighting system functions as a whole to meet its designed specifications.

Frequently asked questions (FAQ's)

Evaluating Light output

The best and most relevant measurement for evaluating LED luminaires for accurate comparison with conventional luminaires is 'delivered light'. This term describes the quantum of useful light that can be delivered to a task area by a luminaire. In LED luminaires, since the light source is unidirectional, the quantum of lumens wasted within the luminaire is minimised and a very high percentage can be made incident on the working plane. GreenBay delivers upto 14000lm to the working plane thereby making it a direct replacement for conventional 250W metal halide solutions.

Thermal Management

LEDs have a cool beam but they do generate heat within the luminaire. For efficient & reliable functioning of the luminaire, this heat has to be transferred away from the luminaire through specially designed heat transfer systems (type heat sinks). Effective thermal management is critical to performance since excess heat reduces light output and shortens the useful life. GreenBay has scientifically designed and developed heat transfer systems to ensure optimum thermal management and reliable useful life.

Absolute and relative photometry

Conventional luminaires are tested with the relative photometry method. In relative photometry, luminaires and the lamps used within them are tested separately. In relative photometry, the lumen output of a luminaire's lamp acts as a reference and the lumen output of the luminaire is measured as a reference to it and hence this is denoted as a percentage. LED luminaires are tested with absolute photometry since LEDs are typicaly an integral part of the luminaire and a separate measurement of the LEDs independent of the luminaire is not meaningful. The approved procedure and testing conditions for absolute photometry are detailed in IES LM 79 -08 publication from IESNA.

Useful Life & luminaire lifetime

The useful life of a luminaire refers to the projected number of hours an LED lighting luminaire will deliver a sufficient amount of light in an application. Luminaire lifetime refers to the reliability of the components of an LED luminaire as a system including electronics, materials, housing, wiring etc. The entire system will last as long as the critical component with the shortest lifetime. GreenBay has been developed fully within Philips to ensure the operational performance parameters are met as an integrated system.
