Philips T5 VHO Extreme Temperature System

Ideal for high-bay applications without climate control

T5 COLLECTION

Lower the costs of your ceilings

With the Philips T5 VHO Extreme Temperature System, you can useT5 lamps in high-bay applications without sacrificing light output due to hot or cold temperatures.

Provides high light output even in spaces without climate control

• Lumen output is >90% from 65˚F to 170˚F (20˚C to 75˚C) due to amalgam technology

• More light over the life of the lamp than a standard 400W HID system

Operates on existing electrical system

• 277V–480V input voltage range eliminates the need for rewiring your electrical system

† This lamp is better for the environment because of

its reduced mercury content.All Philips ALTO lamps give you end-of-life options which can simplify and reduce your lamp disposal costs depending on your state and local regulations.

Reduce total cost of ownership (TCOO) when compared to a standard HID 400W system

• Reduced energy costs—save up to 40 system watts

‡

• Reduced maintenance costs— up to 75% longer lamp life◊which extends the relamping cycle

• Reduced costs since less lamps are needed to meet lumen requirements

1) Rated average life is the length of operation (in hours) at which point an average of 50% of a large sample of lamps will still be operational and 50% will not.

2) Average life under specified test conditions with lamps turned off and restarted no more frequently than once every 3 operating hours. Lamp life is appreciably longer if lamps are started less frequently.

3) Average life under engineering data with lamps turned off and restarted once every 12 oper ating hours on a programmed star t ballast. Lamp life is appreciably longer if lamps are started less frequently.

4) Approximate initial lumens.The lamp lumen output is based upon lamp performance after 100 hour s of operating life, when the output is measured during operation on a high frequency reference ballast under standard laboratory conditions. For expected lamp lumen output, commercial ballast manufacturers can advise the appropriate ballast factor for each of their ballasts when they are informed of the designated lamp. The ballast factor is a multiplier applied to the designated lamp lumen output.

5) Design lumens are the approximate lamp lumen output at 40% of the lamp’s r ated average life.This output is based upon measurements obtained during lamp operation on a reference ballast under standard laboratory conditions.
