LED chip from an LED A19 bulb

LED chip from an LED A19 bulb

This was inside an LED bulb that i had in service outside for about 8 months. It was just a normal 2700K lamp used for outside light and colour was never used.
Bulb recently started to blink on and off every two seconds so I tore it apart and took the LED chip which is still working. Here it is wired up on 12v and 4 toggles to switch between colour.

White plus red makes warmer light and white plus blue makes daylight. All 4 make a nice high cri white. Just blue on will burn paper if placed near it

Don't know what ill do with this. A better heatsink is a must as it gets hot. Might use 5v instead.
