Here’s a quick teardown video of a Ryet E26 400 lumen bulb. It looks like the buyer got a ‘steal’ on the cost of those bulbs in Canada (US$1.50/each) because they’re currently going for $12.99/2 pack for the 1000 lumen version (the 400 lm is likely discontinued and thus the massive discount – which makes for an affordable teardown video!).
Cheapest bulb with full safety listing that I have ever seen. Selling for less than $2.00!
