Greetings - Thanks! And, since you made it this far, I’ll give you the long answer. 
I typically use three different LED strips, and choose which for a project depending on the needs / budget.
Even this small 240mmx240mm base needed about 8’ of strip. The cheapest ‘globe’ brand ($10) was out as it’s only 6.5’, and not the brightest anyway. I went with the Honeywell at $15 (local price - Amazon is only $10), since the base strip is 8.2 foot and it’s my go-to for most usb powered lighting.
It has nice fade and color cycling modes, and also a sound reactive mode, which is cool for my living room since I crank up music on a regular basis. And that’s what the Ghost table and Aquarium projects use, so that’s how I setup the Fire project. And then I also only need one remote, for a bunch of different lights.
However, for the higher end projects I use the WIZ led strips - they are very expensive. For this project a 6.6’ and a 3.3’ foot are $42 on Amazon. Whoa. But it does offer a very nice and dynamic ‘fireplace’ mode. Which I had in mind when I made the Fire.
The Wiz strip is 12v powered through a wall-wart however. But I did make a 12v battery supply using an Amazon adapter and a standard 12v barrel plug.
The Wiz strip is WiFi enabled, and can get really bright, so the battery life may be shorter than desired in super bright applications. It doesn’t ‘need’ wifi though, and once you set up a strip in the app, when powered on it can go to the last known light setting, fireplace for instance, so it still works remotely the way you want.
One other issue using the Wiz is that the LED strip is thick and not terribly flexible, in comparison to the cheap strips. It is however weather resistant, if that makes a difference. But knowing this Fire project was going to be a higher end endeavor, I did specifically make the final base reflector corner pieces with a big enough slot to pass the Wiz strip through.
Bottom line. If I give away the Fire project I’ll just leave the Honeywell strip in it so someone can use any USB outlet or power brick and the simple remote control. But if I end up keeping it, or I suppose someone wanted to buy it, I would change out the strip to the Wiz and set it up for the fireplace effect. That was my original intent, and likely where it’ll end up. I’m thinking it will ultimately live on my bedside table, since the fake fireplace is in my bedroom as well and is usually on when I’m in there. So the Fire would be a nice companion piece.
Thanks again,
