Should I get an led light?

Hey guys. I am going to grow an auto assassin auto flower plant.
I use cfl lights and this really slows down the growth. If I used an hps the plant would grow a lot faster.

I don't have the space for an hps and I wouldn't be able to control the heat anyway.
I was looking at the mars hydro led grow light. It covers an area of 2 feet by 4 feet and my closet is exactly that size.

If I get this led would it make my plant grow a lot quicker than using cfl's.

Not really
But you could definitely build an extruded bar heatsink with say 10 clu048-1212's citizen cobs and do some damage

Its a classic question, most folks will not recommend a mars hydro light due to the lack of efficiency and the amount of problems cheap LED lights are prone to having. Such as diodes burning out or them running hotter than expected.
People assume all LEDs are cooler than HPS and that isn't always the case. In cheap panels it can be the case but because they are not actually pulling the amount of watts they claim. So people look for the most efficient LEDs (as Airwalker is talking about) This means lots of photons per watt and less heat. It also usually means building your own or paying more for a pre built unit.
There are a few folks on here using Mars lights so you can use the search bar and find them. They will grow you some weed and likely more than CFLs will but they are cheap for a reason. Ask the guys who use them and look at the grows.
Really you would get more bang for your buck from something like Airwalker16 is talking about, but that's not always everyones cup of tea.
Which ever way you turn don't make the mistake of thinking because a light fixture is cool that you don't have to vent heat or exchange air. Air exchange is one of the 3 key ingredients to growing weed, without good air exchange( topping up co2 levels within your cab) your plants are going to be limited.
If you post more info on what wattage you are running now and what you are looking at plus what the dimensions of your grow space are then folks may be able to help a bit more.
In the meantime please do some research and find those growing in similar situations as you with the lights you are currently looking for.

basically those mars are good, as good as hps. watt for watt they put out almost as much light and heat as hps...but you cant handle the heat of hps, and you would need 2 of those mars in that space...so no

in fact, watt-for-watt, it is never the case

I've a preference for ViparSpectra over Mars, but that's all personal preference. I have no data evidencing one to be better than the other.

They exist on Amazon and eBay, same as Mars. Chinese based manufacturer, like Mars. Can Mars' 400 equivalent get 675 micromols at 18", 1200+ at 12", and 2400 at 6"?

This video never ceases to crack me up.
I never really got it. There are a lot of people in China. I'm sure they could find a large number of people who were hungry. Anyone could throw a barbecue. I don't see any growers on here flying to China anytime soon. Publicity's all that is, and horribly edited at that. But I'm just talking shit.

If Shannon showed me her Bai Hu, though, I might say at least one thing good comes from Mars. But, alas, there are no girls on the internet.
