5 different Cree Dropins compared – Ultrafire WF-602D 3.6V Cree Flashlight (CR123A) Reviews

Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
Well it's time for me to write a report for those, who might be interested. Find the results of this comparison in the section Other Thoughts.
- Very bright !!!
- Very handy in size
- Very nice looking
- Powerful all-in-one Flashlight for short usage time!
Cons:
- Wow, bad temperature management - it is really getting HOT after three minutes of working time. I have a very bad feeling if I let this little friend burn more than five minutes.
- Getts even hotter if you just let it burn without holding it in your hand and cooling it by this.
- One bad point: The reverse clicky has a bad quality. It is very hard to use, I even thought to replace it.
Other:
So here my great comparison between 5 different Cree emitters. I will list them in the order of the brightness as far as I can tell:
1. Cree R2
2. Ultrafire WF-602D
3. Ultrafire WF-505B
4. Ultrafire WF-502B
5. SKU 11810
My suggestion if you are only interested in the Cree emitter is: Go for the Ultrafire WF-602D. As a bonus you have the nice WF-602D Flashlight body after disassembling it.
Bottomline:
The temperature issue is naturally caused by the little metal body surrounding the flashlight. So the passive cooling part is not enough to guarantee a cool running flashlight. A question rises for me: Does such a hot running flashlight have an effect on the Li-Ion battery? Hmm, I have to investigate that for security reasons!!!
