So I got to ask since I'm transitioning from my 3x3 space running 2x250watt hps.i will be running a now 4x4. Would running 1 315LEC be good enough? Right now I'm considering either running LEC or 300watts of COB's in my new space.
If you can pocket the coin for a Pre built COB fixture i would recommend PLC CXP-250 (2 fixtures) or 1 CXP-420.

For LEC/CMH ...... Sun System is who you go with unless you wanna go D/E CMH

I was looking at doing the timbers DIY kit its 4x 3590's at 300 watts. If I did these Everyone says you need 8. I just don't know how the buds compare to each other. I always preferred my previous LED buds over my hps but you can't beat the weight.

Yes 8 would be best if you want to get the weight your looking for.

Im sure you know COBS are not the same as the LEDs of the past, I'm not sure which your referring to though exactly.

LED's of the past , good old red/blues I loves the frost but the weight was crap so I went back to my HID. I was set on COBs till I started researching again and noticed LEC. They looked a lot cheaper so I wanted to get some good comparison between the two before I kick down the cash.

I haven used a single system light solution since SE HPS. why mix your lights:

LED's Red or blue (cause a blood
It just don't matter
Sucker die for your life
With my shotgun scatters)

COB's

CMH

HPS 400w and lower

the new style MH lamps with amazing blues, its like a DE in a SE bulb.

its like mix-n-match.

pick two, and your side VEG fixture

Why do you say that? It's an attached ballast, so you get more heat in the room. What makes the Sun System better?

\why mix your lights

\
Plenty of reasons to mix lights. An HPS could benefit from more the blue of a MH, LED Blurple will benefit from warm white from COB, COB can benefit from enhanced reds. CMH is probably the first thing I've studied that provides a great full spectrum +UV with efficient wattage use. I agree that there's no need to mix in veg, but I'm a proponent of mixing in flower, if your heart desires.

Honestly i just like there build better ... the up to date versions that are hung vertical and very little heat with the connected ballast and daisy chain able.

Honestly don't own one though because we upgraded to the Double Ended LEC/CMH. Bigger coverage, more power, less heat WIN WIN WIN.

What's the footprint on the DE? What do you run it on? I'm interested, but not sure if it's worth the money. The 315 does 3x3 and a bit more with no problem. I've noticed that the CMH puts off a fair amount of heat, so what's the heat increase between that and the SE? I didn't think the 2 bulb fixtures were worth it at all, but a DE system might catch my attention. What hood are you using?

running the CMH D/E bulbs with a Pro series 750 flex dimmed down.... i spent less on the D/E set up than i would have for the Name Brand most expensive 315 cmh... i get more photons, and more flexibility,

for the foot print well (2) d/e's are rocking a 5x8 nicely .....

IMO 315's only cover a 2.5 x 2.5 unless over lapped or enclosed which i would then say 3 x 3 at best but everyone has different needs.

Curious, if a 315 cmh will only cover 2.5 x 2.5 what does the DE version which is nothing more than two 315 arc tubes in a de package cover?

one 315 in a 4by4 tent and a luxor hood does a decent job although I'm actually running it at 350w.
