please dont give up on the light you chose, based solely on my opinion
at the very least, take a night to form your own opinion, in your own use scenario
Consider it part of your education, what I call a Flashlight $eminar
IF you truly hate it, you can probably return it
it may also be possible for you to pay a fee to someone capable of upgrading the LED...
it would be impossible to find someone on this forum, that only owns one light,
because the first one they bought was good enough for their (evolving) wants and needs..
the vast majority buy one light after another, each time a new variable is discovered, or a new want/need arises.
And I would venture a guess that there are more people here that think Low CRI is fine.
otoh, for the unique task of inspecting automotive fluids, some people add a UV flashlight to their arsenal, and use special UV dye for different fluids.. the poster named RCS1300 has several posts about how he uses his UV light for auto maintenance,

im sending you a private message with a few more details
