Looking for some advice please
I have a small cabin (currently somewhat dilapidated) very near my observatory that will soon be renovated and fitted out to be used for temporary and/or ongoing accommodation (not for me).
A number of light pollution mitigation solutions, like shielding, extended privacy screens and removing windows facing the observatory, as well as decent curtains on other windows, are all being planned in the design of the renovation and fit-out, to prevent/minimise detrimental effects on my observatory operations while the cabin is occupied at night.
Something I was looking for some advice on however, is the best type of readily available (Bunnings/Homehardware etc) LED or normal light bulbs/fittings that could be used in the cabin fit-out (both inside and outside lighting) that would best minimise any effects on the immediate local site light pollution, from an astronomical observations perspective, but still provide adequate amenity for the occupant? The cabin will be on a small to modest solar power system, likely running 240V via an inverter, so conserving energy will be desirable.
Thanks for any feedback
Mike
