Unbranded LED retrofit lamp teardown 2: The cross section.

I got two of these 18w 1200mm 5800k unbranded LED retrofit lamps with an LED Lightpack which I got to convert back to MCF.
I have no use for them so I decided to open one and see what makes it tick. I used unreasonable force to open it so it's pretty much scrap but they were screwed together.

Here you can see the cross section of the lamp. The LED's are mounted quite low down so a large area of the circumference emits light, something which I noted when I first tested these lamps.
Some of the other LED retrofit lamps I've seen aren't as good as this as they emit light from only half of the lamp.
The diffuser plastic is quite flexible and the lamp sags slightly when installed. You can see where the end cap screws in and the damage was caused by me when I pulled it off.

Each LED drops 3 volts and is being ran at about 1.25 milliamps.
There is 96 LED chips in total which are mounted in two parallel strings of 48 LED's in series and I measured 144v DC being output from the driver.
