This is not something I often do, but with the woman and child away, and thanks to Nico (member Nicolaas) who suggested to do some real world testing, off we went to try out some throwers. Convincing proof of my inability to do such a thing is that I do not exactly know of all the beams which flashlight they came out: as systematic as I am in some of my BLF-testing, as sloppy I am at this. I hope that Nico can chime in on details.
This is where we went, north of Amsterdam on a dike shining the beams over the water at some huge electricity poles, hoping not to disturb the ship traffic too much.
At least I know that the very narrow beam is my wooden 5 million cd fresnel lens lantern with dedomed XM-L2 (link), there's a 300kcd dedomedNichia219C UF-1504. and a 175kcd dedomed XP-G2 reflector thrower. Those are my entries, and then there's Nico's ultraviolence at the top of the pole (a fancy Vince modded 600kcd aspheric I think it was).
First a bit underexposed, then a bit over exposed, the reality looked like in between.
And the fresnel lantern at the furthest pole, 730 meter:
And if you overexpose everything you can pretend that they are air raid search lights :
My guess is that the bottom beam is the 219C, but I haven't seen a dedomed 291C in real life. The tint looks very similar to my TN31 that I dropped a domed 219C (5K) in for a bit.
Amazing pictures. I cant believe you did not have any coppers come around and check what was going on. It could well of been an alien invasion. Thanks for posting them up.
