Steve,

Probably the best answer, is to have someone shine the spot into you eyes (after they have adjusted to the dark) from a distance of some 10m. If you find it uncomfortable, there is a good chance that nocturnal birds or mammals will be similarly affected.

Cheers,

Dear fellow nature lovers,



I am posing a question around the use of high powered torches for viewing
our nocturnal counterparts.

What are the thoughts around a super bright rechargeable torch (similar to the 1,000,000 candle power one I purchased just the other day...) doing any
damage to our little friends eyes on a dark night? Not that I would have
done such a thing....

Cheers

PS. Any discovery of a pair of White-throated Nightjars and a pair of Sooty Owls in Bunyip State Forest, Victoria, with burned out retinas since Tuesday
night would be purely coincidental...
