Golf Range Lighting General Requirements Golf Range Lighting General Requirements • Ensure that distance markers are clearly visible• Players able to follow the flight of the ball• Glare to participants should be minimised• Shadows on Tees eliminated for both LH & RH players

To meet the increasing Light Pollution requirements from Sports Lighting, new products have been developed restricting OVERSPILL - GLARE - SKYGLOW whilst still allowing Improved Lighting Specifications and Energy Savings.

Golf Ranges already have an optimum lighting solution in the END RANGE system.

However the requirement to light the flight of the Golf Ball conflicts with Light Pollution specifications & Upward Light is unavoidable.

Consequently: Golf Ranges are labelled as main causes of Light Pollution and often conflict with Planning requirements.

What is this Light Pollution issue?

Light Pollution is Obtrusive Light. Sky Glow (Direct light into the Night Sky). Overspill (Intrusive light outside the boundary). Glare (Visual disturbance towards onlookers).

A conventional End Range system will produce all of the above.

Essential Requirements.

• Consider Light Pollution issues at the onset of the Range Design.

• Examine alternative ways to light the Range.

• Ensure proposals explore and include ways to utilise natural screening to alleviate intrusive light and glare.

• Orientate Ranges away from the “Setting Sun” to ensure adequate contrast of Ball against Sky.

END RANGE LIGHING – Offers the most efficient lighting system for golf ranges. Due to the high floodlight elevations coupled with high intensity floodlights it also produces the most light pollution. The floodlights cannot be screened, therefore, Glare, Upward Light & Light Trespass is extreme. NOT SUITABLE FOR CALVERLEY GOLF RANGE

SIDE LIGHTING - Offers good upward light control but is not suitable for applications when housing is below the range looking up into the floodlights. NOT SUITABLE FOR CALVERLEY GOLF RANGE

BERM LIGHTING - Floodlights at ground level are easily screened, reducing glare & light trespass into properties. Halo effect is significantly reduced when compared to END RANGE LIGHTING. IDEALLY SUITED FOR CALVERLY GOLF RANGE.

Comparison of END Range & BERM Systems. Both Ranges with 4m edge screening.

Installation Comparisons. Based upon a typical 40 Bay Range.

Energy Consumption similar between the systems.

Both put a similar amount of Light into the Sky. but the Halo EffectHalo Effect differs greatly.

Berm Lighting effectively controls Overspill & Glare.

b) Provide a clear indication of achieved Lighting Levels (Lux).

To Meet Planning Requirements.a) Aim to achieve ILE Obtrusive Light Recommendations.

C) Provide Overspill (Intrusive Light) Plots.

d) Provide a System Demonstration to reduce concerns regarding local environmental impact.e) Provide clear indication of method employed to reduce environmental impact.

f) Provide successful case study if available.
