Fresnel Lamp

As an entertainment lighting designer by trade I thought I could re-invent the Fresnel light. Fresnel is a term that describes the glass saving lens used in lighthouses, thus achieving a narrow focus without a massively thick hunk of glass. In theatrical lighting fixtures it refers to a type of body that uses an adjustable Fresnel lens. My lamp is made of walnut, cedar, oak, bubinga, and a few exotic accents. While it has no actual Fresnel lens, it is otherwise completely faithful to the look and function with rotating barn doors, a collapsible “C-stand”, and a very difficult to make gell frame for changing the color. The lamp is an LED that is turned on by touching the brass “lens adjusting knob”, under the body, to 3 different levels.

Very nice craftsmanship and a great, unique subject for sure. Is this the start of a whole line of theatrical lights..? I like it a lot!

Wow, that’s great. I never thought I would see that term on here. Brings back memories of theater work I used to do.

Geez Bill, glad I could take you down memory lane. I will do this again with a smaller light source and implement a sliding mount with an actual 3” fresnel lens – complexity shoots way up but I think it can be done. Can’t wait to see your firetruck!

I will not be building a Firetruck as true to form as your fresnel, even if that disappoints my 5 year old.

As a former lighting techie I love this! As a theater guy I love this! As a woodworker I love this! Do you by any chance have plans for this? I’d love to make this into my bedside lamp.

Put another 20K right there. And get the sandbags!

Yep. Brings back memories for me, too. Great idea and beautiful work.

Beautiful! What’s the scale? is that post about 3 feet tall? Man would I like to make a small one as a work light – just beautiful.
