To use a Dual Voltage Electric LED Bulb E26 in a E27 environment/ socket?

I’m just a guy, no connection to LIFX other than I own a few. This is a community forum. I’d ask them directly via their support channels, although it looks like they may not legally be allowed to sell E27 bulbs in the US.

Sorry, can’t help there. The ones I linked to say E26/E27 in the descriptions, so at the very least you can ask for a refund if it doesn’t work with an E26 bulb, because that would be false advertising. Short of either buying a few and trying it or getting in touch with the suppliers to confirm I can’t think of a solution.

You could probably get away with sticking something conductive in the bottom of your current adaptor, but I wouldn’t personally try that with a bulb I wanted to last, and you’d have to make sure there was no chance of it dislodging and shorting.
