switch to led or keep HPS?

I have about $350 I can spend on a LED that I want to replace my 400w HPS... I dont know jack about LEDs and was wondering should I keep saving up and finish out this harvest or buy one? I dont know what would be the same.

I have a 2x4x6.5 grow tent

SE = replace it
DE=keep it

I got a sweet tasty led t3 2100 I could make you a deal on if your interested

I grow in a 2x4 also.. I just made the switch from a 400 watt hps to a 250 watt 5 cob light from Timber.. ($500) What an amazing difference..more light way less heat with less fans.. plants love it! Save another $150... it is well worth it!!

Keep the HPS, save the $$

I would think two 5 cob kits would work for a 4x4.. I'm not an expert by any means.. some people run 1 cob per square ft or 16 cobs in your case.. talk with Timber Dan.. good man!!

600w of cobs in a 4x4 is pretty on point IMO. Good power savings and good production.

You might struggle to get a decent replacement for that for $350. I would say finish this run and then invest when u have a little more cash.

What are the exact dimensions of your tent?

The reason I ask is to see if you could fit a 315w LEC cmh in there. I think this or 250-300W of COB's would do you well. I use 3x4 and a 2x4 but both of my tents are slightly over sized.

You can build a VERY good 4 COB light for your space with the budget you have, using basically any brand COB's you'd like.

You wanna rock the house in that 2x4 then build a bar style light with 140mm heat sinks and (4) Cree 3590's or Vero 29's on a mean well 320 series driver. I just hung one of these in my 3x3 flkower tent and VERY pleased with it thus far. Very nice and cool temps, no noise from fans and I can put my hand directly on the driver etc and no issues. I am running the Khatod lenses on mine and VERY happy with it.
