Equipment for hobbyist flashlight measurement and learning electrical engineering?

Hi r/labrats, first time poster here. I came by way of r/findareddit, and hopefully I'm in the right place (please forgive me if not).

I'm a budding flashlight enthusiast from over at r/flashlight, and I've become interested in the physics and electrical engineering of my lights now to the point that I'd like to get something a little better than my cheap equipment that I started out with, partly so that I don't need to do runtime measurements of my lights by locking myself in a closet for an hour and spying on the light meter every few minutes while simultaneously pointing my cheap infrared thermometer at the head of the light :)

I've also decided that I'd like to get an oscilloscope and a better DMM to measure the current draw of my lights and other things like the frequency for the strobe/beacon modes, and learn some electrical engineering in the process.

So far I've gotten my list of equipment down to these choices, and I would love to get your feedback!

Light meters

Either the Extech SDL400 or the General Tools DLM112SD. Both of these light meters have a thermometer, and one of my questions here is if the built-in thermometer that comes with these is as good (or as good for my needs) as one that I'd get on a dedicated data logging thermometer. The thermometer would be used during flashlight runtime tests with a surface temperature probe attached to the head of the light, to analyze things like the automatic thermal stepdown that some flashlights have. Right now I'm leaning towards the General Tools instrument, because I can get it with a NIST calibration for pretty much the same amount as the Extech meter without a NIST certificate.

Oscilloscope

This is an area where all I know is that I want one of these, but I have no idea what I need because I am an absolute beginner when it comes to electrical engineering. As I said above, I want to measure things like the strobe frequency of my lights, determine whether they're current controlled or use PWM, and learn more about the electrical side of things in general. The only thing I do know right now is that I'm leaning towards a PC oscilloscope for the convenience that would provide (I want to be able to easily create GIFs/screenshots of the waveforms for things like flashlight review posts). I read a very long review of the Pico 2205A last night, and while I didn't understand 90% of what it was talking about, my takeaway was that it seems like a very good oscilloscope for the price and my hobbyist use cases.

DMM

Right now I just have a cheap Etekcity DMM, and I'd like to make the jump to something better, but not over $250 if possible. I always here Fluke, Fluke, Fluke when it comes to these, and I'm sure one of their more inexpensive models like the 115 or 117 would be good for my needs, but I don't know which one or necessarily what questions to ask myself to make that determination. I will also be using my DMM pretty much exclusively at my workbench, so if anyone has a suggestion for a benchtop DMM that might work well for me in my price range, I'd love to hear what it is and the reason why.

Thank you ahead of time for your feedback, I'm really looking forward to hearing it!
