Finally got enough batteries and all cables made so I can run the VSS-1 and VSS-3 together. They tangled tonight. Who won?? (Again, my cam allows a max of 1 second exposure so use the pics for a relative comparison because the beams are much brighter and impressive in-person.

Hey Billness, your cable works!! I'll ship it out next week. Now I gotta make 46 more solder joints for myself!

Which one is which? Guess before you scroll.

Shot from underneath the beams looking out.

Beamsonly.jpg

Shot from underneath the beams looking back.

The rest you can tell which one is which. Did you guess right?

Center.jpg

Lights are 7 feet apart, shot centered between them.

I thought I was running 3 lights for a moment.

Proof that two beams combined are brighter than one.

Power connection setup for the -3. Need a cart. The shrink tubing I used, is
actually cloth, not plastic. It shrinks just like the plastic does but it remains
the same cloth texture and flexibility when shrunk. Thanks Larry for the
quick-disconnect welding cable connectors idea. They work great.

WOW!

Nice shots BVH, if I had known you were going to do this I may have done a night ride to the top of the Verdugo's and got some shots from there.

Maybe we can coordinate that some time :D .

Take Care,

Nice beam shots, I'm sure your neighbors are just as thrilled!

"Honey I think a tank, make that two of them just parked next door" :D

:wtf:

Re: Tank Lights Tangle, Who Wins?

That sounds like fun MTbkndad. You can be my police helicopter lookout from up there. I need to get those pilots over to the house to see the lights and talk with me so they are not alarmed or think I am trying to light them up. Let me know when you're gonna be up there next. Surprisingly, there is practically no side-spill. You probably wouldn't know they're on unless you look up. I'm amazed. They are SUPER collimated.

Did you guys guess which was which? The camera tells the story but in-person, its very difficult to tell the difference by looking at the beams.

Re: Tank Lights Tangle, Who Wins?

The next time I am at your house I will see which towers I can see from there and that will tell me where to ride to get to the top of the mountain with the best view.

I almost called you this week about getting together for some spotlight lightbox readings and lux at 37.5 feet measurements. I think you had more fun with these tank lights :thumbsup: :bow: .

I was just reading some interesting information about the AN/VSS-3. Apparently it was a military helicoptor light. So this was a tank light vs helicoptor light duel :D .

If anybody had more info I would love to read it.

That is so coincidental! I was reading the same thing about a couple of hours ago after doing a general WEB search on "VSS-3". But it actually started out on the M60 tank, I believe or maybe another tank. In the mid 60's, they were using something called the Helicopter Illumination System (Lightning Bug-Firefly) which consisted of 7, C-123 landing lights kind of "wired/held" together. Then they went to the VSS-3.

:thinking: I think we read the same article. I thought the (Lightning Bug-Firefly) looked really interesting.

Do I get an "A" in "improvisation" for the VSS-3 mounting system? :nana:

I'll have something much more refined in the not-to-distant future.

The pictures do not tell all of the story. Please tell us about it. which one shines farther? which one is brighter? close up and far away. how much brighter, 25% 50%. which one get hotter, runs smoother? tell us what you think.

I walked about 300 feet to the side of the beams and to me, both beams ended at the exact same point in the sky. This really surprised me. I thought there would at least be a little difference in the throw. To my eye, I could not see any difference in brightness between the two beams. The VSS -1 beam was a little fatter around than the -3 (I'm refering to after the two VSS-1 beams converge and beyond) The VSS-1 is the right beam in pic one and the left beam in pic 2 so it is definitely the brighter of the two but again, I could not see it. I ran the lights for about 7 minutes total. Touching the outside of the cases, the -3 was just a bit warmer. Both fans stopped when I turned the lights off but the -3's fan came back on about a minute later. The -1's fan did not. It was probably 60 - 65 degrees ambient. The -3's fan is a little quieter than the -1's fan. I'm really amazed at how similar their lighting performance is given 1.2 KW difference in power consumption - 2.2 KW VSS-1 and 1.0 KW VSS-3. It just does not seem right to have similar performance with that huge difference in power consumption. I expected at least a visible difference and actually more. I really like the spread beam of the -3. There's something memorizing about it. I love the -3 for it's performance in a very "small" package but I also like the -1 because it's a MONSTER and looks the part. So I love them both equally. My recommendation??? I'm sticking to the official CPF motto: GET THEM BOTH!

Bob,

Luv the setup. Amazing beamshot. :twothumbs
So the old school is right! VSS-1 rule!

Twice the power ~= 70% intensity increase ~= 23% brightness increase

Bob,
Excellent job!!!
It would be interesting to see the two beams aimed at something a given distance away.

That could be arranged and would look even better if I was at the top of the mountain shooting the shot toward BVH's house.
WOW an excuse to go on a night mtb ride and play with lights all at once,
oh yeah :D .

There are no local laws that prohibit me from using the lights. Only typical nuisance codes apply. As long as I'm not shining it at someone, a house, a car etc. I'm OK. But the FAA is another thing. That's why I want to get the Police pilots over here to get them on board that I'm responsible and am not going to be lighting them up. I have a pilots license and work for the same company as they do and have someone that knows us both so it's just a matter of getting it done. It is somewhat difficult to shoot straight at a target without lighting up a car or part of a house or something. I'd feel better driving about a half mile to a point low in the hills that will allow me to shoot up to the top of the hills and some relay buildings/towers. I need to get the VSS-1 secured with struts on the trailer before I tow it and I'd like to have my -3 mount. So in the somewhat near future, I hope to do a much better shootout and have a better camera and photographer along, right Mtbkndad?

I should add that the copter is up from dark until 11:30 or so each and every night and they are always within 1-3 miles of my location. That is why I am focused on this issue so much. Two weeks ago, I had it on and saw them coming my direction at about 3/4 mile. I blacked out the light and they ended up making a B-line for me. Once overhead, they lit up my back yard for about 10 seconds but only as they were turning 90 degrees to fly somewhere else. They didn't even make one circle. I said this before; I think/hope they were trying to tell me that "theirs" is better than mine, so to speak. Someone else was listening on the police frequency and they did not call in the incident. So who knows, maybe I'm concerned about nothing.

BVH,

I got an idea, how about if you contacted your local PD while you are at work and will be calling from another city phone and ask about meeting the helicopter pilots. Your you could go to the PD with your business card and ask to meet them and tell them you would like to show them your equipment.

Take Care,

Added section-
PS. When you are ready, just let me know and I will be glad to go and shoot the lights and beams. Dinner will be on me for the priveledge of being able to see these things up close. Now I am really regretting not getting in on the tank light purchase :hairpull: . Oh well, funds have been tight this year and MBC is coming up again soon.

Second added section-
I still really do want to get a shot of your lights from the top of the mountain looking down at your house.
I will give you a call about when we could coordinate that. Maybe some time next week.
I figure I could get to the top of the mountain and then call you. I would have my X1 so I could make my position quite visible. I may be in your area on the weekend and might drive by your house just to see what peaks are line of sight with your location.
