FloodSticks

FloodSticks are small LED floods mounted inside PVC pipe so that the floods can be elevated above snow and hidden behind other props, thereby creating almost invisible light sources. The intention was to angle the light downward to illuminate a relatively small area, thus using the snow as part of the display. The notes here describe the experimental set of four floodsticks; there's no magic to the sizes and dimensions of the materials used. The

Materials:

• PVC pipe (1" diam, thin-wall, 30" long, cut into two pieces, 21" and 9" long)
• PVC coupling (1" to 1/2" adapter, used for the stand-up strut)
• PVC coupling (45 degree)
• PVC pipe (1/2" diam, 8" long - used for the stand-up strut)
• Transparent fluorescent light protector tube (cut to fit/protect the LED)
• PVC or other end cap
• Pill bottle
• Zip ties
• 3watt RGB LED
• 3, 1-watt resistors (LED current control)
• 2-1/2" to 3" length of 1" wide thin aluminum bar stock (LED heat sink)
• DIGWDF RenStick (an ESP-wireless, DC controller)
• 120vac to 5vdc buck converter, 1.5A or greater output
• Wire, plugs, electrical tape, high-temperature and other glues, paint (optional)

Construction notes:

The pill bottle was not originally planned, but the power bucks were too large to fit inside the 1" PVC. A future design would use 1-1/2" PVC instead, thus eliminating the pill bottle and zip ties.

The side, stand-up strut helps keep not only the angle but stabilizes the floodstick from movement

The PVC pieces were tightly press-fit instead of glued; this proved to work very well and allowed later access to the controller

For assembly, the photos should be quite self-explanatory
