The Cause of the POB Foggy Lens is

....when the HID bulb is new and while in use, it emits a steady stream of smoke, or something on the bulb is burning off. After cleaning my lens after upgrading the bulb to 4300k, I actually was able to see this happening. It actually makes sense why some members report the interior of the lens continues to fog up in time.

Anyway, I just replaced my stock 35W bulb with the new 35W 4300k and the difference is like night and day (no pun intended). I tested the modification against my other fully stock POB and it's amazing side by side just how cool or blue a 6000k bulb is compared to 4300k.

Lastly, I purchased several of these bulbs from that vendor on Ebay. The auction was for the 50W bulbs but they are marked 35W 4300k. No big deal for me since the stock POB ballast max's out at around 43 watts anyway. I do like these better since they have a metal base rather than the plastic. Since they are metal based, I didn't use the metal retaining ring from the stock bulb. Does anyone know if this was okay for me to leave it off?

Well, I have to get back to modding my Power On Board spotlight. I'm relocating the switch because I've gotten tired of every time I pick up the spotlight I accidentally turn the darn thing on. I'm also adding a volt gauge and a much better SLA battery better designed for high amperage devices and about 12 watt hours more power (108 total watt hours of power). I chose this route because I wanted to be able to use the stock battery charger and circuitry since it smart charges.

very cool, post up a tutorial....

Here is a brief pictorial of relocating the switch from under the handle to the rear section of the Power On Board Spotlight. Also, I went with a 50w 4300k HID bulb rather than the 35w 4300k bulb. I liked the more uniform beam better in the 50w version bulb.





First thing I did after removing the business end was snip the
wires off the switch. They are soldered on and had to be cut.




I added some extension pieces of wire, soldered and shrink
wraped them. The longer lengths were then easily pushed
through the hollow of the handle and out the back of the light.





I replaced the existing wire loom to tidy things up and
the business end is ready for the upgraded 50w 4300k bulb.
Reinstalling the bulb was not photographed, sorry.





Sorry for the blurry photo. I reused the existing switch and used my
dremel to cut a new rectangular recess for the switch. The size was
approximately .69" long and .49" wide. The spot I chose for the switch
location worked great. Although, if I use it in the rain, I may have to
find a way to cover the switch. The upside is when I grab the light, I
won't accidently turn the darn thing on anymore not having the switch
mounted under the front of the handle.





The switch relocated and the rear of the
unit back together and ready for action.







My wife was great to help me take these photos.
As you can see the difference between a stock POB
on the bottom and my upgraded 50w 4300k bulb on top.
The top beam is much warmer and more desirable to me.






Again, thanks to my wife Diana for taking this photo for me. This shot
was only 50 feet away, but was taken to show the difference in color.
The stock POB 6000k on the left and the modified POB 4300k on the right.
You can easily see the increase in output and color definition. All photos
were taken with the digital camera on f/3.5
