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.

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.
