  • Strip
  • String or Strand?
  • Orb or Sphere?
  • Globe (can be on bullet or round PCB format)
  • "Bullet" or "Christmas Light" style? What else to call these?
  • Terms that could be used:
    • LED - Maybe this refers to the package (eg: a 5050 WS2812b LED is referring to the package of 3 actual Diodes inside the 5050 Chip...)
    • Diode - Maybe refers to individual diode like the R inside an RGB...
    • Pixel - Refers to an individually controllable element. Usually consists of at least 3 "Diodes" in 1 or more "LEDs", sometimes multiple will be ganged togerther to light up as one "Pixel"
    • PCB - Usually refers to one Pixel with many LEDs / Diodes on it (like round Orb PCBs and such)


  • 30 LED / Meter
  • 60 LED / Meter
  • 144 LED / Meter
  • Usually 5V, though 12V usually means 3 LEDs per pixel.


  • Base Package
    • Bullet Shaped
      • Sometimes in "Icicle Light" formation (short strands of LED hanging from a main strand)
      • Sometimes in "Netting" formation where strands are zip-tied together to form a diagonal net
    • Square Shaped
  • Optional Covers
    • C7 / C9
      • Clear
      • Milky
      • Faceted
    • G10, G20, G30, G40, G50 (number is globe diameter in mm - 40mm is roughly ping pong ball sized)
      • Clear
      • Milky


  • Usually circular PCBs with multiple LED packages on each side (3 RGB LEDs per side on 35mm)
  • Usually 35mm or 50mm diameter
  • Usually 12VDC or 24VDC
  • Sometimes 40 bulbs per string (usually no pass-through connection)
  • Meant to dangle vertically, sometimes called "360 degree" and/or "milky"


  • Sometimes are strips with plastic domes attached at intervals where there are ~3 LED packages in a row, then blank space until next dome


  • Sometime called "Meteor Tubes" or "Cascade Lights"
  • Sometimes are Strips inside a plastic tube, strips may be flex or rigid PCB
