hi people i know ill probably get some hate for asking this but i have seen it done before just cant find the old posts on it
i have a mars hydro 300w (135w true wat) crappy led that i would like to swap the board out with something decent like a QB board
i know the drivers are shit and its super old technology but i have one sitting around going to waste and if i can spend less then $100 to upgrade it. i see that worthy
id prefer not to use cobs even if they are better due to the fact the wiring is more complicated then just taking the existing positive and negative wires and plugging them in to a QB. id even prefer if i can slot it in the original housing if i can get the board to have similar dimensions. can anyone help me out with some information or links to boards i could use. also preferably boards that can be use to veg and flower if not at least used for veg
Pull the light apart and get a look at the drivers.
Take a pic of driver/drivers, they usually have a sticker on them stating voltage range and current.
Any cheapo drivers I've seen are usually ~550 to 600 mA and 55 - 100v but they vary slightly.
Here's one
I've a couple of these in use for QBs and cobs.
3 x citizen 1212s at 20 watts each for example.
I'd need to check the QBs wattage but think it's around 34 watts.
