Adding more Spiders

I have a 4x4 Gorrilla tent, and 2x 4x2 Gorrilla tents.
In the 4x4 is a Spider Farmer SF-4000, and both 4x2 tents have a Spider Farmer SF-2000.
The word is those lights are sufficient for the amount of square feet. In my opinion they fall short of perfect coverage, falling off fairly quick at the edges.
This morning I ordered a Spider Farmer SF-2000 to add to my SF-4000, and 2x Spider Farmer SF-1000's to add to my existing SF-2000's.

The plan is to attach the lights to a 1"x1" aluminum angel stock on each side, so they can both be adjusted as one fixture.
I'm kinda new to LED, I'm a old School HPS and MH grower.
Can anyone give me an idea of what these amounts of LED light would compare to HPS and MH? 400 watts, 1000 wstts?

Led growing compared to hps is so different...Temps required are higher at canopy and ambient.
Growing style has to change to suit...ie depending on board, depth of light penetration can be an issue( hence I use Timber cobs, great penetration)
Finding a balance between your preferred grow style ie open and free, scrog, etc and the type of light you use
is going to be the determining factors.

So, the only one able to make that comparison will be you and how you grow. There is a definite learning curve switching over.
