Her posts are always informative and helpful in On Topic areas, and she's got it going on in OT too 
I'm now going to take a couple minutes and find some random threads she's posted in to check to make sure I'm right

Those are all some that I found from threads that have been active within the last two days. I should have been keeping track of some of the very good examples I've seen in the past, those are just some I found from a couple minutes of searching.
I've consistently been impressed by the wide range of topics for which MS Dawn can give helpful information. Her answers are far more valuable and informed by real life expereinces than approximately 99% of the other replies I read
.
Just seems like she should be Elite by now based on the quality of her posts.

Mag is the bose of flashlights.
There are many different types of emitters. Traditional LED (T1¾ package) are the most common and produce up to approx 10 lumens each if driven conservatively. Efficacy is always on the increase and Nichia corp seems to be taking precedence in this realm. ALL white LED's are actually indirect injection devices. The LED is a narrowband semi monochromatic device and this is not well suitable for a general illumination device for human eyes. Back in the 90's it was found that a deeper blue emitter when covered with a fluorescent substance whitish light could be produced. These early white emitters had lots of color issues and often very blue.
Today's emitters while far from perfect have much higher efficacies and better color rendition and color temperature balance. The newest Cree devices rival CFL's but produce a point source light. These manufactures are promising better efficacy in the future and hundreds of lumens per watt is possible! :Q
T1¾ based lights will either use an array (hornet's nest) or have an optic to shape or even collimate the light. Luxeon based products can use optics too however deep reflectors will provide much greater throw and better control over the light. There are drop in replacements for traditional flashlights that are based on a side emitter and these work well in mag lights that use conventional incandescent bulbs.
The price of the light determines other features such as digital regulation of the circuitry ensuring the output stays as bright as possible throughout the life of the power cell, flashing, variable power, signaling, etc. Case materials may also be comprised of other uncommon materials such as Titanium. Aluminum machined casings are often Type 3 Hard Anodized with Chemkote treatment on the insides. These higher end products will often feature a thick optical window that's anti reflection coated and hard tempered. These lights can cost hundreds of dollars and will provide years of reliable service. The biggest problem with the smaller lights is losing them!![]()

LED's are most certainly dimmable. If the designer uses a good circuit, color can be maintained as well. Incandescents are really not dimmable IME as the color shift to red is very bothersome.
:shocked: too much knowledge FTW
