Flac beam, ( METAL HALIDE ), 20 degree spot beam, silver grey, G12, 70W, IP65



The Flac is a surface-mount 20 degree spot  beam  primarily designed for energy-saving up lighting of tree, building façades and churches. Flac an  has an adjustable stirrup bracket for mounting on walls or concrete ground.  It uses a 70 watt single-ended metal halide lamp and polished reflector to project a 20 degree symmetric circular beam for up lighting larger trees: the central 20 degree beam is ideal for up lighting from beneath and is complemented by peripheral light spread for coverage of canopies.  Use 150w models for larger trees or where the trees are further from the viewpoint to compensate for the distance. Where the outer canopy is dense and the inner canopy & structure is more open, up light the central trunk & branches with one Apollo 36 degree spotlight and position other Apollo spotlights to illuminate the outer canopy. Look up through the tree you propose to light - if you can see up through the branches, then light will penetrate the canopy and structure as well. If not, use up lights to light the tree externally. Lighting large trees is a black art: test the position of up lights with a temporary wiring set-up before final installation. Lighting of trees with very open canopy may be brighter than desired - consider Apollo 35 35w metal halide spotlights or Elipta halogen spotlights with Power saver 50w lamps as a lower power alternative. This advice is for general guidance and subject to branch & canopy structure and foliage density, colour & translucence.

Lamp type

Ceramic type CDMTC70 70 watt single-ended 3000K warm white metal halide lamp for is recommended for long lamp life and colour stability for purple/red/yellow/green foliage trees. HQITC35K4 white lamp gives cooler lighting effect suitable for trees with blue/grey foliage such as some pines and cedars. The lamps can not be switched on and of in rapid succession, they need time to warm up and cool down.  ORDER LAMPS SEPARATELY.

Installation

Stirrup bracket for mounting on walls or an optional ground spike. 20mm IP68 gland provided for connection to mains supply. HO7-RNF 3 core rubber cable recommended for connection to armoured supply cable via a separate weatherproof junction box or underground joint kit (not supplied)

Environmental impact

Care should be taken for the environment and local wildlife to maintain the ecological balance. Insects, bats, wildlife can all be effected by  light pollution. The warmer colour spectrum of  ( 2,700 Kelvins ) does not interfere with insects and general wildlife as much as the blue colour spectrum of light around 6,000 kelvins which can disrupt their normal night time activity. This alsoapplies to bats where a anti glare light fittings works better as well as reducing the overall light pollution in the area. You must also be mindful of your neighbours and the effect your lighting can have on them and shining a 500w tungsten halogen flood light in to their windows at night will cause them distress. Try to keep the light in a downward position and local to the items you want to illuminate and even if you want to illuminate tall trees it can be done in a sympathetic way by placing a ground buried or surface spike flood light directly under the trees to illuminate the canopy. Some light fittings also have a anti glare shield fitted to reduce light pollution.
