Wanna stay cheap?
Open amazon and get a viparspectra or a Mars Hydro panel, both 300 version are under 100 euros.
They are plug and play, no need to diy

this is 10 $ for 100w chip with driver...i will try 3x 70w for 30 $... for my grow space 2.5x2.5

so what do you think will it work like hps250 or viparspectra 300 ...I think better

It's only your house that's going to burn down, not mine!

why @blake9999

You get what you pay for.!

omg so noo noo then...I think I m going with hps

Why don't you save yourself the trouble and get a quality light that you don't have to worry about for a long ass time. You keep making these threads.

the cheap diy stuff you are posting is probably actually less efficient than both mars and viper

2.5 x 2.5 feet?

no

not enough light.

that is not going to be very effcient at all youd need 3 of those to fill the space and they might only last a year or less at those high currents

it doesnt make sense to put all the diy time in if your components are cappy to begin with. components ae only part of the cost, as time isnt free. (electricity isnt free either and so theres no incentive to build crappy inefficient setups)

multiple people post every single day with "this is cheap, will it work?" There is this imaginary idea that because something is an LED it is the same as every other LED out there, and thus cost is the only factor. thats like comparing the cheapest harbor freight wrench to a snap on. both will turn a bolt (for a while at least in the HF case)

you get what you pay for! led is not the good choice!

You need at least quality COB's like Citizens, Luminous or Cree. These cheapo's are 90-100lm/w, Citizens are at least 155-165lm/w, even better when driven low.
You already got all that info's and now you come with another cheap chinese chip around the corner.
Get quality parts and make a quality light. It last you at least 5 years not only one and we already told you, you need ~150$ to make a cheap but bad ass 200w light for a 2,5x 2,5' tent.
