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 ?
Sunday, September 21, 2008
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 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.

steel columns for public lighting
While there are no visible welds, the columns will have a longer life time. The non-interupted structure and the rounding on the total length of the column will take care for a better stability of the column and luminiare.
cilindrical stepped (variable diameters)A classic column, which has been used for decades, is the cilindrical stepped column. This type of column can be delivered in different variants: post columns, columns with fixed or mountable brackets, foldable column, lighting columns with banners, etc. All types of columns can be supplied with wedges, ground plate or base plate.The cilindrical stepped columns can be produced out of one piece till a length of 22 meters. If you need lighting columns with a length of minimal 22 meter and it is necessery to hot dip galvanise the column, then we have to split up the column in two sections (due to the length of the zinc bath) We are happy to inform you about the correct solutions.

It would be difficult to imagine any community without street lights. However, selecting fixtures that promote pedestrian and vehicle safety without over-lighting the surrounding landscape can be a challenge.
Most U.S. communities are committed to reducing light pollution or artificial 'sky glow,' the light that surrounds an urban area. Sky glow can result when light sources distribute light directly above a fixture's horizontal plane or indirectly from light that reflects upward from nearby surfaces. Advanced refractors and reflectors help meet today's 'dark sky compliant' mandates by directing light exactly where it is needed.
Reducing Light Pollution
Fixtures are now classified in four categories:
- Full cut-off. Light is not distributed at or above the fixture's horizontal plane.
- Cut-off. Aminimum amount of light is directed at a horizontal plane and light above the horizontal plane is within 2.5% of the total lamp lumens.
- Semi cut-off. Light above the horizontal plane is less than 5% of the total lamp lumens.
- Non cut-off. Aconsiderable amount of light is visible above the horizontal plane.
Today's fixtures feature precisionsegmented optics in a variety of light distribution patterns and lamp sizes and styles. Some fixtures, for example, have flat glass lenses to meet strict environmental standards; others are available with either vertical lamps for wide area lighting or horizontal lamps for roadway coverage.
Types of Lighting
Four types of lighting are used for most area and street lighting: fluorescent, metal halide, and high- and low-pressure sodium. LEDs are also becoming popular, but many communities are waiting for more extensive field testing before switching to them.
Fluorescent lights are often seen in commercial buildings. They are energyefficient, but operation in very cold temperatures can be an issue.
Metal halide offers a cool white light, is efficient, and uses long-lasting bulbs. It has good color rendition and is popular in street lighting.
Low-pressure sodium produces a yellow-orange light and is more efficient than high-pressure sodium. While the lamp's deep color makes it unacceptable for street lighting, it is useful for tunnels or near observatories.
High-pressure sodium is also efficient with longer-lasting lamps. It produces a warm golden-white color ideal for street lighting while delivering more light per Watt of electricity.
Finding a Fit
Many state transportation departments set standards for street lighting based on safe light levels for traffic. The most common choice for busy roadways has generally been a tall pole and a 'cobra head' fixture with a high-pressure sodium lamp.
However, in business districts that promote pedestrian traffic to restaurants and shops at night, walkway and streetscape lighting must be warm and inviting while addressing safety concerns. Lower intensity lights on shorter, closely spaced poles can light public areas without harsh shadows, which can be perceived as threatening.
Traditionally styled fixtures can enhance a revitalized downtown district by combining a vintage appearance with contemporary technology. These fixtures are available with full- and semi-cutoff light and a choice of light sources.
The most popular streetscape fixtures are made from heavy-wall cast aluminum construction and have a 3-mil polyester powder coating. In areas where vandalism is a concern, municipalities often select vandal-resistant fixtures constructed with metal cages around the lamps and finished with anti-graffiti coating on the pole and lamp head.
Selection Resources
During the initial stages of a new lighting project, a limited number of luminaires and related components should be identified for final selection. Manufacturers can provide resources such as design CDs, photometric information on mounting height recommendations and fixture spacing, layouts to assist with setting light levels and distribution, and submittal drawings of the selected assembly,including technical detail.
If there is a requirement to match existing luminaires, poles, or bases, the design team and in-house tooling department can be consulted about feasibility of reproduction. These services are typically available at no cost. Tooling costs for custom products can often be eliminated due to the large inventory of custom tooling available at major manufacturers.
When your community is ready to renovate existing lighting or is planning a new civic project, you can find environmentally sound fixture choices that offer the latest styling, technical advances, and low-cost maintenance features.

Making sure that luminaires remain as maintenance free as possible is very important to lighting engineers, and there are many different ways to seal the optical and control gear compartments to achieve this. We asked Bryan Shortreed, Engineering Support Manager at Urbis Lighting, about the different options available.
Why is keeping the optical compartment sealed so important?
"For a luminaire optical compartment, the choice is simple. If there is any ingress of dirt or moisture then the performance of the luminaire is affected, as the maintenance factor is reduced.
Additionally, there will also be a requirement for cleaning the inside of the optic, which will increase the time taken for maintenance. Therefore, it makes sense to choose a luminaire with an optical compartment tightness of IP66."
control gear compartment
Control gear consists of either a ballast, ignitor and capacitor(chinese reference ) for conventional control gear or an electronic ballast. There are often other electrical components such as a photocell or monitoring device.
The life of an electrical component is strongly related to the temperature at which it runs. If we take the conventional ballast as an example, the ballast manufacturer will specify a maximum temperature (TW) at which the ballast should be operated to give it a life of 10 years. Typically, if the ballast were to run through its life at 10 degrees above this figure then the ballast life would probably be halved. Similarly, if the ballast were to run cooler than the TW value through its life, then it would be reasonable to expect the ballast life to be significantly improved. All of the other electrical components behave in a similar manner."
