Singapore night race will not be dark…

  
Singapore F1 track 

Here’s a new picture showing just how bright the lighting will be at the inaugual Singapore Grand Prix this year:

The Singapore race organisers trialled a new lighting system recently along St Andrew’s Road in front of the Padang - where the cars will hit 260kph during this year’s race.

More pictures below:

They’ve also tested out the lighting system that will be used for flag warnings:

Concerns have been expressed by drivers and fans about the safety of racing at night - but from these pictures it looks as though the race will be very well-lit.

According to the organisers the pit building is 65% complete and resurfacing work on parts of the circuit are and resurfacing work on part of the track has begun.

The 2008 Singapore Grand Prix will be held on 26-28th September. It will be F1’s first night race and is expected to be followed by Malaysia in 2009 and possibly several other Asian circuits in the near future.

How to select Street Light Poles ?

How to select Poles ? 

Poles should initially be selected, according to lighting application needs and second, but equally important, according to the structural requirements imposed on the pole by the required lighting fixtures and bracketry. Before attempting to make this selection, it would be helpful to have an understanding of the terminology, such as steady wind velocity, gust velocity, EPA, special wind region and maximum weight. Then a step-by-step procedure can be followed to select the proper pole for your particular requirements.

Steady Wind Velocity

This is the maximum steady wind velocity expressed in MPH likely to occur in a specific location. Refer to Iso-Tach wind map on the next page for the wind velocity in your location.

Gust Velocity

Gust velocity is a momentary increase in wind causing a whipping action. In all cases, Hubbell pole calculations include a 1.3 gust factor over steady wind velocity. This means that poles designed to withstand winds of 80 MPH will withstand gusts to 104 MPH.

Effective Projected Area

Effective Projected Area (EPA) is the exposed surface area of a fixture or bracket multiplied by a shape factor which varies depending on the shape of the fixture or bracket. For example, a large rectangular fixture will present more resistance to the wind than will a round or cylindrical shape.

Special Wind Regions

Some locations such as mountainous areas and areassurrounding the Great Lakes exhibit wind velocitiesconsiderably higher than the surrounding areas. Consult local authorities to determine maximum wind velocities and select equipment accordingly.

Maximum Weight

This is the maximum allowable total weight the pole is capable of supporting. Its value is determined by the total weight of the lighting fixtures and bracketry for your application requirements.

Pole Selection Procedure

With an understanding of the parameters for poleselection, you can follow this simple step-by-stepprocedure and, with confidence, select a pole to meet your particular requirements.

1. Determine the site location and steady wind velocity by referring to the Iso-Tach map. If the location falls between Iso-Tach bars or on the 70 or 90 MPH bar, use the next highest wind velocity; i.e., 80 or 100 MPH. If the steady wind exceeds 100 MPH, consult factory.

2. Total the EPA for the required luminaires andbracketry.

3. Total the weight of the luminaires and bracketry.

4. Compare steps 2 and 3 with the maximum allowable EPA and weight as shown for the style, material and height pole required. The maximum allowable must be equal to or exceed the totals from steps 2 and 3.

Pole Selection Concerns

Reference the Pole Selection Guide and Installation & Maintenance Concerns on every pole catalog page.

Caution: These selection methods are guidelines only. Hubbell Lighting assumes no responsibility forselection and recommends you consult qualifiedprofessionals for verification of overall system design, site suitability, foundation considerations and applicable code and regulatory conformances.

Maintenance: The facility owner’s/manager’s regular scheduled maintenance program must include initial and regular follow-up inspections for structural damage, broken welds, tampering, nut loosening, missing wire covers, dangling electrical wiring, internal or external corrosion, foundation settlement, excessive shaft deflection and vibration for all lighting poles. Immediate repair or replacement may be necessary.

Overloading: Do not overload poles by attaching flags, banners or any items that can add excessive wind or mechanical load to designed pole assemblies.

Observation: Installation and local area conditions can dramatically affect lighting pole performance. Excessive vibration may result from some wind and mounting conditions. Only individuals with local knowledge, who have observed or inspected the site can effectively evaluate site specific issues. Consult the factory for information on vibration dampers, special corrosion, foundation settlement, excessive shaft deflection and vibration for all lighting poles. Immediate repair or replacement may be necessary.

Lighting

Lighting has become increasingly important for commercial and retail property owners for increased sales, security and safety for tenants and customers. Pole lights are an integral part of these three issues. Site lighting provides necessary lumens to a parking lot or parking garage. Dealing with the ongoing maintenance of these light poles has always been an issue for property owners, property managers and maintenance personnel. Maintaining a brightly lit parking lot has always had it's challenges. The lighting design for new installations of parking lots have now been placed in the hands of photometric engineers. Photometrics optimizes the maximum amount of light to an area with the least amount of light heads and poles. There are many different types of light heads available in different voltages and lamp wattages to the end user. With all of these different selections there now is an option to add Retropole to your new or existing light pole to maximize the ability to replace a ballast or lamp as soon as the light burns out without the need to schedule an electrical contractor. Commercial and industrial lighting once installed is often overlooked until there is a problem with burned out lamps. Retropole offers immediate replacement of lamps or ballasts without the need of waiting for many lamps to go out before making a service call feasable. Lighting designers focus on making parking lots look attractive but often neglect ongoing lighting maintenance which ultimately is left to property owners to deal with. Retropole lighting products are the solution for this problem. Insist on Retropole for new or redevelopment projects for easier property maintenance after building contractors have left the job. It's sleek attractive look works with any lighting design whether it be contemporary lighting or traditional lighting and is color matched to any light head or light pole.

Outdoor Light Fixtures

Outdoor light fixtures for most parking lots are on a 25 to 30 foot light pole. These fixtures come in many shapes and sizes with a variety of voltages and lamp choices. Typically these pole lights are either high pressure sodium, metal halide or mercury vapor. Lamps go out usually in a year, however, hid lighting suffers from a reduction of lumens over time resulting in a loss of light output even though lamps are still burning.

You can identify which type of light you have in your parking lot by the color emitted by your lamp. Metal halide lamps cast a white light, high pressure sodium lamps emit a yellowish hue and mercury vapor lamps project a light blue color that works nicely as landscape lighting. These pole lights, as different as they seem, have one common flaw. They are inaccessible.
