LED lightings for logistic warehouse
A logistic warehouse with large plain area is use for storage of goods and raw material consigned by importers, exporters and wholesalers. They often have cranes and forklifts for sorting and moving of goods that need to be despatched to the ultimate consignees as designated by the consignors.
Picture on left exhibited the lighting profile of the premises after using NOVETE® G400 high intensity canopy highbay for reformation of the existing lighting arrangement. Task performances was significantly improved as compared to the traditional HID luminaires, that the following data is of reference.
Outline of the project | The logistic warehouse with plan area of approximately 12000m2 were illuminated by traditional highbay fitted with 400W HID lamps coupled with 120° cone shape reflectors. The operator initiated to reform the existing lighting arrangement due mainly to economizing the cost of maintenance. | |
Adoptive luminaire | 200W high intensity G400 canopy highbay, model G4040A-329W200K5. | |
Mounting method | The luminaires fitted with U shape bracket were mounted on the horizontal steel structural of approximately 12 meters high. | |
Lighting layout | Average 10 square meter per light | |
Task performances | Average illuminance on floor area | 306 lux (Eav) |
Perpendicular illuminance | 459 lux | |
Workplane (0.85m above ground) | 349 lux | |
Uniformity | u0 = 0.68 | |
Specific connected load | 18.9W per m2 | |
Comparative features | Daily operation | Average 10 hours daily of 360 days |
Power consumption basing on compatible task performance basis | G400 @ 757.8kW per light/annum | |
