Your going to get 1000 answers. A removable driver is always a good idea. But it's all in how you use your light and size them. I use
HLG lights and they can be ordered with a removable driver option and a extension cable. My lights are all way more powerful than most people need or want. And my tents are very tall. And I keep the drivers on the light. In my 3 x 3 tent I have a 650R ( 640w tested ) in it. For most out there it's a 4 x 4 light. But the method to madness allows me to keep the dimmer down on low settings in the summer and keep my light close to the plant with near perfect light spread. Or come winter time I can raise it high in my tall tent and raise the dimmer up to higher setting and heat the tent with it and keep my office grow room comfortable and still maintain any PPFD level of light I could conceivable want and never tax the light at all. My 2 x 4 tent is the same with two 350R's ( 700w total tested ) in it bolted together. I don't think I have ever ran my dimmers above 50%.
There are a lot of good lights out there now days. I've even been thinking about picking up a couple of
AC Infinity lights. A EVO 3 for the 2 x 4 and a EVO 6 for the 3 x 3 to just play with and see how they do. They have lots of functionality and control and through the Pro series controllers. But I don't like there published light spectrum. Not enough red with lots of green, yellow and orange. All useful but not what I want. Then it dawned on me,,, of course they don't have the red I want that's why you buy the submental lights. Then it's not such a entertaining purchase for me.
The most important things I can tell you is don't cheap out on your light. And get more than you think you need. You don't have to go overboard like I do. But the new norm in reality is 40 watts a square foot now days. So that's a 650 watt light for a 4 x 4. And get a light with a big footprint. You want the big footprint so you have even coverage in your tent/grow space. Enjoy and Good Luck!
