Outdoor light - total teardown
Added 2020-08-06 17:39:06 +0000 UTCI think this is the first time I've depotted one of the little waterproof drivers. The potting material was surprisingly crumbly and easy to remove.
This light features the usual mystery-earth, but with an added twist.

As I just posted on Youtube. I got this style heatsink in a 20-pack but mine have a COB on chip with no external power supply. As a 20-pack they were quite cheap at around $11.35 a light and were shipped inside the US, so I had them quickly. They are still up for sale at https://www.ebay.com/itm/202014967743 Mine were also earth, the earth wise connected to a tapped screw hole inside the plastic lens. and I measured it by touching inside the tapped hole for the plastic cover. Power draw was only about 30W but they were plenty of bright.

2020-08-09 16:58:54 +0000 UTCHeat and acetone have their own merits. Using boiling water is less destructive to the component housings if it works.

2020-08-08 16:10:20 +0000 UTCI believe acetone is the weapon of choice.

2020-08-07 17:21:08 +0000 UTCClive, try boiling water for depotting, I have liberated and thus reverse-engineered many a module. It's a real pain but most resins go very pliable and can be picked abd peeled to bits under the water. I use a fan to blow away the steam too to not fog up my (safety) glasses. Lol at the YT title "Shady ebay light"

2020-08-07 15:02:36 +0000 UTCWow that potting stuff was actually pretty great. Just enough to encapsulate the circuitry yet crumbly and removable for repair. -must be a mistake

2020-08-07 09:05:36 +0000 UTCThe potting gunk is probably some waste material from industry. :)

2020-08-07 06:42:53 +0000 UTCHopefully that one is an isolated 12V module inside.

2020-08-07 03:11:27 +0000 UTCLook at that schematic again. GND and ZCS are connected together between the current sense resistors and the inductor. Weird???

2020-08-06 21:56:39 +0000 UTCI just received a bunch of LED meteor lights and the use the same power supply

2020-08-06 20:48:47 +0000 UTCWas it just my TV, or when Clive was moving the light around the straight lines on the case went a bit weird

2020-08-06 20:20:51 +0000 UTCNice looking lamp, unusual way of mounting the driver
2020-08-06 20:16:08 +0000 UTCMystery earth with a twist. Shaken not stirred π
