I have an X60, actually two now, 2nd under different branding, think bought from BangGood. Also as the Sharp Eagle XC, sold at GearBest here. This is a pretty old light, though they've gone through revisions. More recently I bought the Warsun CT9T, and it's been updated from previous CT9T models I've worked on.
The original X60 design, all Warsun designs in fact, suffered from a very poor LED alignment piece that blocks output. Lumens was significantly down just from the poor design. Also thought the head diameter is bigger than C8's, it's reflector inner diameter is the same as a C8. Basically you are getting a deep reflector C8. It's a good light to mod, but stock - I would never recommend one unless it's the redesigned version without that black LED alignment structure. You lose like 200 lumens.
Good picture of it is here: https://budgetlightforum.com/t/-/27801 in the OP.
See post #64 here: https://budgetlightforum.com/t/-/26123 on my X60 mods.
Looking at the TomTop product page from the OP, it's a redesigned version - the LED alignment piece is a typical white centering piece - much better!
Also for that price, cheaper than the Sharp Eagle XC at GearBest. GearBest marked the XC out-of-stock after they offered one to me to review, and I refused, citing the false advertised specs they had (SS bezel, AR lens, etc.). This was months ago.
I don't really trust this brand, knowing how arrogant the owner is, but it's a well built, hefty C8 class light with a nice side switch. I find the side switch excellent in quality.
