>>6869702If all you're gonna do is solder LED's into control circuits a soldering station is overkill.
Buy a cheap soldering iron with a (replaceable tip) with a rubber grip (important for comfort if you plan on doing this for hours on end), a stand for your new iron and a roll of leaded solder.
Don't forget there's a lot of nasty chemicals involved with soldering make sure you do it a well ventilated area and with at the bare minimum a fan to push all those shitty fumes away.
Watch this as primer for safety while soldering
