LED vs HPS 3.5x6.5

Got a 3.5x6.5 tent up .
Veggin a few plants under a t5 atm.
have a 600 wat hps Or 2 That i can swap in for flowering.
But I’m thinkin I want to switch to cob or qb To ease the electric bill.

I’ve seen some reviews of
Timbergrowlights and growerslights.

Wat would the community recommend?
Wat would be minimal to adiquite ?
This wud be just for flower.

Gunna get a 2x4 tent for veg. Feel free to recommend a light for that also.

Never seen a 3.5x6.5 tent before. Makes it hard for me to suggest the best light for that space.
Aim for about 35w per square foot.
Both companies your looking at are awesome, possibly 3 x 260w QB kits would fit well since they cover a 2x4 or 3x3 each.
Not that familiar with everything timber has to offer, but I know they are quality.
@RainDan can offer up some suggestions if he hasn't already.

You could use the HPS in the middle and bridgelux EB gen2 strips covering the outside edges? Cheap as chips, then if you're impressed/have more funds you could fill the tent with strips?

Check out ledgardener's example builds using strips if you're interested ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux/

So the HPS sits central covering 3.5'x3.5' and you've got 1.5'x3.5' on each side = 10.5sqft to cover with led.

10.5sqft x 35w/sqft = 367.5w of led/183.75w each side.
