It seems that the Ultrafire 502b is considered somewhat better, at least for mods, than the 501b.
What is the difference between the two?
I wasn’t paying enough attention on ebay and did not realize that there was a xenon 501b. I also did not notice that a 502b I bid on was red light.
Dumb me, and I expect no one else will buy them so I am stuck with two I don’t really want.
So I wonder about a drop in that is not very expensive.
Don’t sell the red led short! I have few and really enjoy night-hiking neighborhood trails with them. I own a 502b and it has a Philips Luxeon K2 bulb. I got no complaints for $10
i just bought 5 502b u2 for $11ea and am planning on using them for stocking stuffers. they make great go to lights and you do not care if they get trashed. been using the 502b for edc currently with never a problem.
Maybe I will like them after all. I am not sure why I buy flashlights as I do not get out at night very much.
Thanks for the replies. What is the difference between the two models; 501b and 502b.
