If this was your first time running it, that big blob might just be it breaking in. Mine wasn’t very impressive for at least 4-5 runs with the stock bulb.
Honestly though, might be easier to just get a voltage converter like this one and use the stock bulb: BESTEK Travel Adapter Voltage Converter 100V to 240V Step Up Transformer with 4-Port USB Charging All World Contries to US Travel Charger (White) https://www.amazon.com/dp/B07QS3J6K8/ref=cm_sw_r_cp_api_i_uNX9Eb42Y5AA9
I understand that part. what im wondering is if you used that same address f2m gave you as the billing address?
Also, found another guy on this subreddit say he was going to use this to convert the different voltages. Another person he was answering in the replies mentioned it be good.
