The cheapest smart light bulbs right now
The ranking loads here, each price with the time we checked it. A store price shows for 48 hours after our check and an Amazon price for 24 hours after Amazon returned it.
All 39 smart light bulbs, with each one’s lowest price
A to Z. Every model has a CSA certificate for the exact model and a US store link. The price column shows the lowest price we can show right now for one new unit.
How the ranking works
- The ranking is by the lowest price we can show for one new unit. A multi-pack, a used or open-box listing and a store page where you pick the variant are never ranked.
- A store price is read from the store’s own product page for the exact model and variant we link to, in US dollars, about twice a day, and shows for 48 hours after our check. A store that states the item out of stock is skipped.
- An Amazon price comes from Amazon’s product data and shows for 24 hours after retrieval, with its time. An Amazon listing reported unavailable is skipped.
- A smart light bulb with no price we can show right now is listed below the ranking with a link to check its price at the store; it is never ranked on an old price.
- Ties go to the first store row on the product page. We rank prices, not quality: the cheapest is not a recommendation.
Before you buy the cheapest smart light bulb
- Check the model and the pack at the store. A price for a two-pack, an older model or a version made for another country is a different product. Match the model number on the store page with the product page here before you buy.
- Count the hub a Thread device needs. 8 of these 39 use Thread and need a Thread border router; if your home has none, add its price. A Wi-Fi smart light bulb joins your home Wi-Fi instead.
- The checkout price is the one that counts. A store’s price can change between our check and your checkout, and shipping and tax are extra. We show each price with the time of the check.

Questions about cheap Matter smart light bulbs
What is the cheapest Matter smart light bulb?
It changes with store prices, so this page does not print a price in its text: it ranks all 39 certified models by the lowest price we can show right now, and the first card is the cheapest at our latest check. Every price carries its check time, and the store’s checkout price is the one that counts.
How are the prices ranked?
The ranking is by the lowest price we can show for one new unit. A multi-pack, a used or open-box listing and a store page where you pick the variant are never ranked. A store price is read from the store’s own product page for the exact model and variant we link to, in US dollars, about twice a day, and shows for 48 hours after our check. A store that states the item out of stock is skipped.
How current are the prices?
We read store pages about twice a day. A store price shows for 48 hours after our check and an Amazon price for 24 hours after Amazon returned it; after that the price leaves the page until a new check confirms it.
Does a cheap Matter smart light bulb need a hub?
It depends on its network. Of these 39, 8 use Thread and need a Thread border router, which Google describes as a special hub that connects Thread devices together, and 30 use Wi-Fi and join your home Wi-Fi instead.
