Light Flicker Detecting Top

Prints (0)

Description

Use this device to identify energy inefficient light fixtures by their low frequency flickering! All you do is spin the top and look for a blinking bluish line to see if you could be using a better light fixture! Why This works: Fluorescent light bulbs flicker at twice the AC frequency because the magnetic ballast driving them is directly affected by the AC current peaks. So 60 Hz AC = 120 Hz flicker. Newer more efficient solid state fluorescent tube lights flicker at a much faster rate. This top has high contrasting colors spaced in such a way that when spun at low speed it will create a frame rate interference, just like when you look at your TV through a digital camera. The photos taken with the bluish lines are what you see with slow flickering light, the other two photos used sunlight which doesn't flicker and just makes a red white blur. NOTE: Some LED's have low flicker rates and will give you a false positive. Don't throw away your energy efficient LED's!
