I thought this was an old thread as many I read are. I am planning on getting one of these MHled say the 600w for a 4x4x2 Tent.
I am currently running a 600 hps in a cool tube and going to take the "Leap of Faith". Seems to be the best idea as i only run my 600w power at 75 Percent.
How many watts do I need for my tent to have sufficient lighting?? Also I scrog everything so I would like Full coverage of my surface which is 2x4.
Any response will be helpful don't wanna drop alot of doe on a system that will not be enough to cover my area or have overkill.

I was also thinking 2x 300w Fixtures for more even coverage. They are on ebay for $93.49 Save alittle money gain alittle coverage. any Thoughts?

I think im going to go 2x 300w since I can save a few bucks. They are from ebay seller ledlightseller 89.94 for 300w Sounds like a deal to me.

please excuse my last post got your numbers mixed. So do you use an inline fan or can I get away with less? How much heat do these Led's Actully put off ive read different post saying they put off little heat and others saying they aren't much cooler than HID.

There's a LED section on these forums that has a lot of good information you might want to check it out.

sry mate its a hard question to answer as I can only go with my own situation and yours maybe very different...what you want is optimal growing temps and you may or may not need an inline fan to achieve that...

the led doesn't put off much heat at all compared to a HPS light

Your eBay leds will cost as much to run as your hps. Heat wise 600 watts input to cheaper leds will also provide about the same amount of heat as well. If upgrading an hps you need to go to quality panels to out perform. Ventilation is very important, no question, get an inline fan

I have a 6" Inline fan and dont need to outperform my hps just need sufficient amount to get enough to last me.
Just bought one since its on sale gonna wait to see since I feel that is the only way to be sure.
Keepin the fan and the hps. I was thinking I could have an enclosed system with co2 if the heat wasnt an issue.
Thanks for the info ballist.

It probably will make a nice veg panel or supplement the hps with it but it does sound like your really chasing yield. To replace a 600w hps 400+ watts of good quality leds beware how they market leds. Most just multiply the number of leds by their maximum dissipation but typically they are running at about 50% of max.

Yes I Decided to return the led I bought and am going to look for a better one after asking the seller a few important questions (only runs 100w Actual power). I had got a few 3w leds to make a veg panel. After reading about these Chinese sellers taking Americans for fools I decided to test them and these 3w seem to be 1w .

I'm looking to be buying from marshydro since they seem to be more honest.

I'm not so much chasing a huge yield as a decent one im trying to beat the heat when summer comes and quiet the inline fan to be more stealthy.
I'm going to be starting school here soon and just wanna get everything as discrete as possible but still produce enough bud to get to the next harvest.

When i said i will be keeping the hps I meant sitting on the shelf ready to go back in the tent if this led doesnt cut it.

Ive grown with a 150w hps and made it work so im not asking for a miracle just looking for a better solution to my issue (Sound+Heat)

I just started flowering with a new California light works SolarStorm 440
in a 2x4x7 tent. There is far less heat than an HID You will need some air movement
I get away with a couple of 6" fans inside the tent.
Clip on type fans.
