I forgot I'd already done a similar video to this. But here's a new version with all the same pitfalls.
I'm getting better at swapping these LEDs. The trick seems to be to clean all the pads so they are flat and then put a tiny touch of solder on one leg of the LED so it can be quickly "tacked" in place when positioned correctly. (Like a tack weld).
Then press the LED down firmly while soldering the other lead and then go back and resolder the original lead with more solder while still holding the LED down firmly.
In this case I was replacing three white LEDs with two blue and one green to give a deep cyan colour.

That is a really nice lamp Clive. I wish I had your ingenuity. Your really good at all of this, I don't know how you've not retired as a millionaire as of yet.
Gotta love that wee schmear of thermal compound!
Little dab'll do ya, big gob'll screw ya (AvE)
We definitely need a BigClive T-shirt with the channel thumbnail logo on the front and famous BigClive sayings on the back like, "I'm not 100% sure.", "What's the worst that can happen?", "Let's take this to bits, shall we?", "Let's see if it goes bang.", etc.
Any ideas for submersible low voltage pool lighting? RGB or blue would be great.
I'd like to make one with either green and uv leds or UV and red leds
Those pink bags are not anti static. You need the silver bags.
LEAD BASED SODDER FTW
Solder braid burns your fingers and holding coppered slab of aluminium while you fuse fluxed lead into the surface all hurts. He does tell you how to not get zapped though.
Looking at you struggle with those LEDs, I'm thinking about holding them in place using an alligator clip with a piece of wide rubber band glued to the teeth of the clip. That might work.
Very nice I wish it was for sale.
Some random thoughts on soldering. Clive, you seem to have to have heat resistant fingers. Yea for 60/40 lead / tin multi core rosin solder. I laid in a big supply of the good solder when the ROHS regs came into effect – other substitutes just don't get it. I noticed in this video that you flicked a blob of solder from the tip of your iron to your bench. I solder and unsolder a lot and in the course of a life twice I went to flick a blob of solder from my iron to the bench and because liquid solder is slightly elastic it flicked on the rebound and landed right on my glasses. Glad I was wearing them! Cheers, and thank you for your vids – don't change a thing…
I thought that was a bag of giant glitter you had at the beginning there until you turned it over.
hi Clive, just out of curiosity what voltage are the leds ? and what type of circuit would you recommend to get them to work off of 12volt dc ?
try some desolder braid, even a pump would clean that wire right off
I want to see a video explaining the difference between daylight and warm white leds from what I can tell is its just the color of the yellow coating on them.
