Be very careful with this. Light sources can emit all kind of peaks of light you might not notice. For example a LED might look red but can also emit some infrared.
While it can be very bright in the open sun, your eyes will compensate for this. A light source which emits harmful amount of IR and little to no visible light will probably not elicit this reaction and damage your eyes without you realizing until it's too late.
Infrared lasers are particularly dangerous for this aspect.
I insist that the "OP" is mostly being alarmist without thinking about all the 620-700 nm (and deeper infrared) exposure we perceive throughout every day.
