Dimmer I'm using. https://www.amazon.com/dp/B09DT173R1?ref=ppx_yo2ov_dt_b_product_details&th=1

Got it Wall <- Grangier voltage converter <- UK power strip <- US to UK Adapter <- Dimmer <- UK to US Adapter <- Lamp.

Been working well so far, you don't see a problem adding two adapters between the US plugged dimmer right?

Probably, assuming all your devices are autoswitching.

I took a power strip like this with me to Europe in 2015 and 2017, and it was a godsend, as my hotel room in Brussels only had one available power outlet, and the apartment we rented in Paris had very limited outlets. It was life-saving compared to just bringing plug adapters.

I plugged in a US Anker USB charger (like this), a couple USB devices and a cheap EU phone with European plug. No worries.

Your input power would be dependent on the voltage in your home. I personally do not know what Canadian voltage is. If it is like the US, then yes, 110. If it is like the UK, then 220.

I wish you had stated WHICH Mathmos lamp you purchased so that I could tell you specifically which item below to purchase. Neo's do NOT need the convertor. All of the other lamps do.

As far as the plug is concerned, I use the following power strips for all of my Mathmos lamps EXCEPT the Neo's...

1. Buy a Universal Power strip if using more than one lamp. I personally use Krieger and buy them from Amazon for $20.00. You can plug in 6 lamps with it. I recommend the Krieger. I have had no issue with mine. Walmart also s

If you have a Neo lamp, then you can buy something like the following in order to plug it in and you will NOT need the converter...

1. If you are buying a NEO lamp, no converter or power strip is required. They work from 100-240vac with the appropriate plug. All you need is one of these from BestBuy or Walmart. $10.00 and it plugs into your existing outlets. You may already have an old one that is not being used. Check out old electronic items you may have lying around (i.e. DVD players, CD players, radios, etc.).
