Walmart Holiday Time plug-in Christmas lights with green wire: Lead-free!

This newly-purchased (2018) set of Walmart brand “Holiday Time” 16 Function Multicolor Mini Lights (pictured above – with 150 lights and a green wire strand) was tested with an XRF instrument. It was not disassembled for testing, only accessible parts that one would normally touch when using them (installing them or operating them) were tested.

Disclaimer: It is always possible that there is some Lead (or other toxicants) in components that are inaccessible with the XRF (without disassembly) or in components that are extremely difficult to test with XRF, due to their shape and/or size (for example the actual tiny lightbulbs themselves).

UPDATE: I had originally had LED in the title, but – bucking the current nearly universal move away from incandescent lightbulbs to [more energy-efficient, less-breakable] LEDs – it turns out that these little guys are not LEDs, but rather old-fashioned tiny glass lightbulbs.

They had the following XRF readings (with all accessible components tested):

  • Lead (Pb): Non-Detect / Negative
  • Mercury (Hg): Non-Detect / Negative
  • Cadmium (Cd): Non-Detect / Negative

NOTE: This set differs from the Walmart set posted earlier (the battery-operated set), in that there is Antimony (Sb) in most of the components. Antimony is a common ingredient in fire retardants. 

ANOTHER UPDATE: With additional testing of this product (prompted by my findings of Arsenic in the Target brand of lights, LINK) I also found trace arsenic in the hard green plastic at the base of the bulbs in this set of lights. Specific test results showing levels of Arsenic and Antimony are listed below.

I also want to be clear that even with these considerations I think these modern lights are LOT better choice than their vintage (or even 10 year old) counterparts that are generally very high Lead!

Scroll down through all of the photos for the additional specific XRF readings for each component.

Green Wire:

  • Antimony (Sb): 8,188 +/- 184 ppm
  • Chromium (Cr): 442 +/- 198 ppm
  • Bromine (Br): 1,154 +/- 35 ppm
  • Zinc (Zn): 615 +/- 48 ppm
  • Copper (Cu): 521 +/- 63 ppm
  • Iron (Fe): 406 +/- 93 ppm
  • Titanium (Ti): 2,964 +/- 1,649 ppm

Green Hard Plastic at Base of Bulbs:

  • Antimony (Sb): 24,900 +/- 800 ppm
  • Arsenic (As): 54 +/- 18 ppm
  • Bromine (Br): 74,300 +/- 2,500 ppm
  • Zinc (Zn): 2,466 +/- 101 ppm
  • Vanadium (V): 861 +/- 295 ppm
  • Titanium (Ti): 1,496 +/- 478 ppm

Green hard plastic controller enclosure:

  • Antimony (Sb): 267 +/- 23 ppm
  • Bromine (Br): 810 +/- 12 ppm
  • Tin (Sn): 447 +/- 19 ppm
  • Nickel (Ni): 15 +/- 7 ppm
  • Iron (Fe): 38 +/- 17 ppm
  • Bismuth (Bi): 29 +/- 9 ppm
  • Titanium (Ti): 5,754 +/- 308 ppm

Green hard plastic part of the plug:

  • Antimony (Sb): 1,189 +/- 31 ppm
  • Barium (Ba): 147 +/- 92 ppm
  • Selenium (Se): 16 +/- 3 ppm
  • Bromine (Br): 35 +/- 3 ppm
  • Zinc (Zn): 774 +/- 20 ppm
  • Copper (Cu): 1,467 +/- 30 ppm
  • Iron (Fe): 22 +/- 14 ppm
  • Titanium (Ti): 999 +/- 209 ppm

One sample test of bulbs (multiple colors in frame):

  • Antimony (Sb): 4,277 +/- 196 ppm
  • Barium (Ba): 2060 +/- 446 ppm
  • Chromium (Cr): 297 +/- 196 ppm
  • Bromine (Br): 390 +/- 24 ppm
  • Copper (Cu): 95 +/- 46 ppm
  • Iron (Fe): 976 +/- 135 ppm
  • Bismuth (Bi): 185 +/- 33 ppm

Posting a product on my site does not necessarily mean that I recommend that product. It is an opportunity for consumers to educate themselves about potential toxicants in consumer goods. My hope is that with each and every post you will read the information, learn about issues or related considerations and then used that information to make an informed choice about the things you use in your home.

As always, please let me know if you have any questions.

Thank you for reading and for sharing my posts.

    Would it be possible to test the LED version of these plug in Holiday Time green wire lights? I just bought a bunch (cool white) and (red). I will provide a donation for your time, just send me the link. Thank you!
