The home depot ones are ok.. 3 pucks for around 35$ now (they were 27$ when I first started buying em). I got 3 sets and it was a pain in the butt to get the 3 sets to match up color wise.. some were "bluer" than the rest.
I recently got IKEA dioder 4 pack pucks for 40$.. and they seem alot brighter than the home depot sets. They are also much lighter and can be attached with a double sided sticker.
