The biggest problem is they are ALL made in China with varying degree of quality. I purchased a set from one of the wicked light's bigest competetor (who are located in Austin and claim to be the original/best quality). They sent me junk that burned out within seconds of powering it on.
What I don't realize after reading the sale pitch about quality, best, etc, is they don't stand behind thier product. You have to click on the FAQ to see the "small print" which limits the warranty to 14 days and you pay the return shipping (even if it's broken out of the box) - The wife never let me hear the end of that one.
To make matters worse, I found the same flashlight, which the other guy charged me $124 for $23 at lightmalls.com:http://www.lightmalls.com/uniquefire-hs-...battery-charger
But before you run off and buy the cheaper version keep in mind it's ALL
made in china.... I recomend you find a retailer who sales the product you want and will stand behind it (like Cabela's).
Now, as far as green vs red, I tried them all (dedicated CREE LED flash lights) and hate them all. My eyes are getting too old. The pure green and red LED lights lack the light spectrum to provide details for my old eyes.
For my daughter's youth hog hunt in July (Yeah it was toooo hot), we had four different types of high output LED lights, and we found that it was very difficult to see any detail at 100 yards at 1AM! The raccoon that showed up detected both red and green, but it was too late for him...he won't be stealing corn any more corn.
In the end I pulled out the backup flashlight (Standley 10000 lumen white LED) and attached it's RED filter, which provided a more balanced light spectrum that my old eyes liked, and it worked the best......Just ask the hog who didn't see anything before his dirt nap at 3AM!.http://www.candlepowerforums.com/vb/showthread.php?398664-Stanley-1000-lumen-rechargable-flashlight
I'm done with the poor quality, chinese junk, red/green LED flashlights, and in the future I'm planning to switch completely over to Streamlight with their red/green light filter.
