I run a Mars TSL 2000 in a 2x4 and couldn’t be happier

Agreed! I just set this up in my 2nd 2x4 and I'm really happy with it.

If you are in a more southern area of the us, Spend the extra $$$$ on Mars SP series or any others that have good heat sinks. You'll save more on AC and it will be easier to control your temps. Some of the TS series you can mount the ballast outside which helps but you still get a lot of heat just from the lights. Myself I'm not a fan of expensive lights cause the technology changes so quick
