I knew it

I don't throw hardly anything away and I've struggled to find a use for plastic coffee cans.
Cut a hole in the bottom>inserted bulb thru it and screwed it in...instant snoot.
Ya gotta use LED bulbs...no heat emitted.

I would be tempted to get a can of black matte spray paint and paint the interior of the container, unless you want a red colour cast in your light.

[chauncey]

That's on the agenda...just wanted to make sure heat wasn't a problem.

I use LED floods too.

For better quality, may I suggest Colombian

The only other comment I have is that your snoot has a very large diameter, so you will be casting a fairly broad beam.

This is a shot of the one I own and the outlet diameter is 5cm / 2".




Normally one wants a very narrow beam of light. But who am I to say; experiment away!

The hottest part of my LED light is the voltage convertor ciruitry and it really doesn't get all that warm.

Manfred...what it that thing? Haven't seen it before.

It's a commercially produced snoot.

Material - sheet metal (steel) with a matte black paint job.

Used to cast a narrow beam of light. In this case, I used a blue gel in the shot.


Same equipment, but slightly different setup to get this shot:

You can easily make DIY kits mimicking these Honl speed grids. In a couple of minutes I made a couple of various lengths with various size straws and cereal boxes. There are for flash units, but something similar can be made for your lighting gear.

Nice.

Venzer, I think I have this one site saved in my drafts box.

[chauncey]

Venser...lots of diy folks use Pringles chips tubes filled with straws.

[Loose Canon]

So what if you put the lid on it, Chaunce, with a hole cut in it? You could even put your Pringle’s can in the lid, or a toilet paper/paper towel tube filled with straws?

But you gotta lose the red interior color for sure.

[chauncey]

Before I do anything else with this project...does the length of the snoot tube affect anything?
I would think that the longer and narrower the tube would tend to more focus the light...?

PS...Gonna coat the inside with black tape.

The one on my snoot is 2-3/4" long x 2" in diameter.

Essentially you want it as short as possible, so as to minimize any light loss, plus long enough so that there are no "hot spots" from the light source.
