You could use Parametric Search Engine
There are so many lights that you may have to do your own digging.
Try your best at selecting something not too expensive. After a while you’ll get a better feel of what you like / dislike and if inclined order a new model.
And you may add the feature of on board USB charging and the type of switch. These filters are in the search engine.

Edit (August 20th. ’19): There is this arbitrary list of flashlights by Zak that may be a starting point.
