Have you tried putting your lights on a dimmer?

But I voted for on the wall. Basically I would hang them in the "corner" where it meets the wall and ceiling to keep it looking clean.

I think it will provide decent indirect light but you might want something to diffuse the light or create a channel around your wall and project the light up onto the ceiling. Kind of like a cove light, it just depends what kind of look you are going for. Will they work, yes.

I have them on my wall and they aren't too bright or distracting. My buddy did put them in his basement too on top of some trim and they look nice too.

I put mine all the way around the room on top of the base boards (floor trim) and it looks cool

Exactly what I did. To get rid of the glare, you cannot have direct light. uplight is key.

Baseboard works great if you either don’t mind seeing the LEDs or provide shielding (can get pricey). Baseboard install gives a nice, indirect, color wash to the walls

Top of wall works great because it removes the LED light from direct view and also allows the entire “band” to be visible if you so desire.

I chose top of wall. I’m about 5” down from ceiling. LEDs sit in a 3” MDF molding I routed using a 1/2” rabbet bit. Dirt cheap mounting method as I just ripped 4x8’ sheets of MDF down to 3” and made nearly 200’ of molding for under $100.

Thats awesome, now I gotta start milling some trim....

I mounted mine to the bottom track of my drop ceiling then diffused them with marquees. The led’s are on a dimmer, what you see there is 25%. I also use 24v leds because then you can run a much longer strip without worrying about voltage drop.

Like others have said, the key to using LED strip lights is diffusion - you have to diffuse that light or else it is a bit overwhelming if you can't dim it. I achieved a nice look in my room by attaching a small furring strip to the wall about 4" down from the ceiling, placed the LED strip (cheap Utilitech strip from Lowes) on top of it, and then attached a 1x3 trim board about a quarter inch away from the face of the furring strip to allow the light to diffuse upwards and downwards. Initially, I attached the 1x3 directly to the furring strip but it forced all of the light upwards which made a distinct blue line on the ceiling. I wanted a softer effect so pulling the 1x3 away from the wall created a much softer effect because the light goes upwards and downwards. To get the 1x3 away from the furring strip I used 1/2" long metal tubes (they look like straws) and ran the screw through the face of the 1x3 and through the tubes into the wall. This keeps the 1x3 away from the wall. Sounds complicated but it's very simple.

No problem. Here's are few more images.
Rough cut and routed moldings (before paint)
These MDF pieces were simply nailed to the wall using my Paslode airless finish nailer
I've include an image of he Excel engineering drawing I made before routing them
Also a picture of
I was a little worried about the LED tape sticking to the (very dry/dusty) surface of a routed piece of MDF but they worked great and have stayed down

Ok, forgive the ignorance, but can’t you just do this:

Not as fancy as MT45’s obviously, but my ceiling is a bit too low to do that style.

Those solutions can work for most folks. Works best for shorter installs. The aluminum channels are a nice clean look too.

I could not use the LED solution because my total run length is nearly 200 feet. When you run LEDs at that distance you encounter voltage drop and must accommodate for it. I ended up running 24 volt LEDs instead of 12 and buying huge (600 watt) power supplies (2 of them). I could have used the aluminum channels but found I could make mine at about a third of that price.

Still, what you shared are great solutions for most game rooms!

Any amazon recommendations on some adhesive backed chasing leds?
I’d need just under 50’ to go around the top of the wall.
Thanks!
