Good to hear, I'm debating between these and the Vision X tantrum's.
I know this response is a year late, but hopefully it'll help someone else in the future.
I used to have the Vision X Tantrums on my last tacoma. THey were ok. I liked that they came with so many lights, but they quickly turned murky from water/elements. Plus they weren't super bright. As 01Tundra stated, they're more like mood lighting. Quality was decent for what you pay, but they let water in and the wiring was bulky and cumbersome.
My buddy just installed some litespots on his JK and I am blown away by the quality. THe magnet is pure genius and super strong. Plus the LEDs are 100% waterproof, being that they're completely enclosed in the epoxy. Build quality is incredible. I was really impressed. Install was a cinch and I just ordered 12 for my current rig. I felt that 6 LEDs weren't quite enough to light it up well enough for my liking, so I bought two kits. 12 should be more than plenty.
One thing about LEDs is that they don't put out nearly the light that regular old $10 rock lights put out. It's a white, soft light, and in my opinion, it requires more lights to light up the area well. I love the current draw on these things though, you can run them all night and still be able to start your rig in the morning.
