Apollo, 150w Metal Halide, narrow spot beam, IP65
E94150N is a surface-mount narrow beam spotlight with a 20 degree beam angle primarily designed for energy-saving up lighting of trees, tall columns or church spires. Apollo has an adjustable stirrup bracket for mounting on walls or an optional ground spike. The lens has "through-flow" slots to allow water to flow off the lens even if pointed directly upward or fitted with a glare shield. It uses a 150 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. Where the shape of the tree falls within a 35-40 degree arc, use E94150S to cover up to 30m high, subject to density & colour of canopy & structure: perception of brightness varies between different people. If the tree has a wider spread, especially over 10m, use 1 or more E94150W 60 degree spotlights for a fuller effect. Use 70w models for smaller trees . 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 Powersaver 50w lamps as a lower power alternative. This advice is for general guidance and subject to branch & canopy structure and foliage density, colour & translucence.
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.
Ceramic type CDMT150 150 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. HQIT150K4 white lamp gives cooler lighting effect suitable for trees with blue/grey foliage such as some pines and cedars. ORDER LAMPS SEPARATELY.
