Good ideas. If I need to go heavy-duty, my local hardware store has split shaft collars like the clamps that ruedaloca shows and also the rubber-covered clamps like worwig shows.
These LED lamps are light and I can probably use a light mounting system. What I envision is a couple of the rubber covered clamps holding a vertical plate with the lamp fastened onto the plate with 3M automotive trim tape.
