Need help choosing a light?!

[Ross4Twenty]

been looking at spider farmer and Mars hydro, I need something that is equivalent to 600w hps, currently running 250w hps but wanting to buy myself a led light

There’s that many models etc I just don’t know which one to buy considering I’ve never used led before

I’ve got a £150 budget , thanks

Will the light be used for veg, flower, or both? How many square feet are you trying to light?

Sorry! I’m currently two plants in a 4ftx4ft tent , but I think a 3x3 should suffice? Or should I get a 4x4?

It will be used for just flowering as I’ll always be using a 250w hps for veg

How much canopy space you want is a function of how much yield you want per grow. In soil and without supplementing CO2, one ounce dried per square foot is a reasonable approximation. I want at least 30 watts of LED per square foot for soil and ambient CO2. At least 40W/ft² with hydro and/or CO2. Other features I want include detachable drivers (to get heat out of the tent) and continuous dimmers. I don't know how to get you within your budget buying new from Mars or Spider Farmer. You should be able to find something used around there.

For a 4x4 if you chose spider farmer you would want a SF 4000, a SE 5000 or a G 5000. Those would give you good light for flower across the whole 4x4 area.

That's a little spendy for the OP's budget, but if you can find one for £150, by all means grab it.

I run these for $239.00 USD a little over your budget but you can dig up $40.00 more, (they were on sale a week ago for 199.00) I run these 1 plant 1 Light very good fixture.

or 2 of the sp 150's in a 3x3 would work fine for 1 big plant (trained correctly) a friend of mine uses 8 of these in a basement grow, he brings in good crops every 10 wks. (2 for $180 USD)
