I found an inexpensive source for high temperature insulation

[mudman cj]

For those of you wanting to insulate your hotwire for:

-extended runtimes with a hotdriver
-reduced bezel temperatures to minimize risk of burns
-possibly keeping Li-ion cells cooler while running

I would like to recommend that you purchase some high temperature insulation. You can order some high temperature ceramic fiber insulation here for only $3.80. It can cost as little as $5.87 after shipping with USPS 1st class! This product is a little thin at only 1/8", but you can coil a strip of it around in a spiral to build up greater thicknesses.

I can see it keeping your Li-ion cells a little bit cooler,
I can see extended runtime with or without a HD.
But don't you want your bezel to run hot since that means that your bulb heat is being wicked away from below wherever you installed the insulation? Because if it doesnt wick the heat away wouldnt the heat just remain inside the flashlight host?
JimmyM had sent me some insulation to try this out and I must admit I never got around to trying it out - so its about time I give it a try.
Thanks for the reminder.

Hey can you maybe use a smaller font size? :shakehead

Mudman, thanks for the link and post that you can actually read. I needed to get some of this.

Thanks DM51, for making this thread more friendly to the legally blind. At least they can see that we are having a good time here.

Edit: OK, PC disclaimer: I am not insensitive to those with disabilities-I have a friend that requires special software to be able to scan his computer screen and read it. Despite this computing hurdle he earned a degree in computer science.

Luckily you can hold down CTRL and MouseWheelDown to enlarge font size on the fly....cause there was no way I was reading "Size 1" font size....anyway, I have two sheets of that fiber coming. Thanks again.

I have been using ceramic blanket material in all of my hot wires. I use it even in a mag charger in liue of the mica disc that is sometimes used on the original socket. I pack it behind reflectores and around the base of pedistals. Here is an example:

Edit: Thanks to JimmyM too for setting me up with the idea and material a while back too.

Lux - On 'MY' monitor both fonts look similar in size-there was no shouting (large fonts) intended and i have tried to include screen shots which even show that my font size appears smaller han Mudman CJ's - Oh yeah and if you look you can also see i have "NOT" edited my initial post.
So from my end I have no idea what you are referring to.
Maybe gremlins at work?
