Need to contact and administrator. Not sure if in right forum. Will give more details to admin.
Here is the updated parts list that is still needed to fix my xml 650 light.
5 single 10 watt cree led chips.
Simple.
Here is how I came to this conclusion. This story will also be posted on the 420 magazine forums.
First lets look at a front view of the light with the LEDs on.
Those dim lights you see are leds failing. With less than 5,000 hours of use. The light is also on it's own circuit to negate surges. Ex: having a chiller and light together on same circuit. Compressor kicks on, light gets dim, compressor off, quick flash.
Now let's make this into a crude schematic/drawing of the light layout.
The dot's represent the 10 watt cree leds. The connecting lines are 3 chip led strip sets. Single dots are single leds. The colors represent the brightness/condition of the leds. Yellow very bright, black very dim, orange dim. I only have 2 3-strip leds with a bad diode in each. So now I have and extra 3 strip that wasn't needed.
Now let's take a look at the chips close up. I was told that most of the leds looked fine. Only 4 or 5 are burnt out. I counted 9.
Led # 3 (part of 3-strip)
This is the beginning stage of failure. Bubbles and cracks are forming from within.
Led # 7 (single chip)
More advanced stage of failure. Looks like bubbles inside of a bubble. Kind of like when you blow through a straw in a glass of milk.
Led # 9 (part of 3-strip)
The yellow chip is no longer visible. Dark amber color. This isn't even the worst one yet. Let's keep going.
