Kaidomain has a WF-501B with a red Cree XR-E P4. Could this make it better than the DX one?

Actually place an order.
I tried several times but there was something wrong with the checkout.
I then gave up..it was a while ago though.
Also, I find the site very difficult even compared to DX which is hardly award winning itself.....

According to a local cop who is also a certified bike safety instructor, only red lights to the rear and white to the front are legal in WA state. He also said no one (in our town) is going to give me a ticket for my monkey electric or down low glow (green) lights on a bike. He said the reason is confusion caused by multiple colors (on cars). From my experiments with the down low glow, it would be great to have a very strong red light shining down on to the pavement behind your bike and a white one near the front (in addition to your normal rear and front lights). Then cars know where you are on the road. The blinkies and the white front lights can be confusing for cars when it comes to depth perception especially when it is raining. Next time a car is coming towards you in the dark, notice that you can tell WHERE the car is not by looking at the lights but by seeing the lights reflected off the pavement and other objects.

KD must be terrible then, cause DE is pretty crummy in my experience.
I bought 4 lights from DE, of which 3 were messed up in some way. I fixed one with O-rings, and returned another, which was replaced in about 8 weeks by another yet another defective flashlight.
I bought 2 sku 16092s from DE - the two they sent are not even the same light. Different parts, modes, one is great, the other kinda sucks. My second (negative) product review was not posted - they clearly edit feedback to their advantage.
There is no way to make intelligent shopping choices with DX - their descriptions are erroneous, pictures wrong, no feedback, etc. Add weeks of waiting and there is just no way the most patient shopper can be happy with their deals. A cheap flashlight is not cheap if you have to replace it by buying multiples, hoping probability will eventually reward you with a good flashlight.
To their credit, DE's lithium batteries and chargers seem to be pretty good. Evidently even they can't fu#k this up.
IMO DE does just enough to appear to be honest, but in the end you're simply wasting time and getting frustrated just to save an insignificant amount of money.
From now on I buy from US sellers.
BTW Shining Beam is excellent, check em out.

The Cree P4 datasheet doesn't have any red LEDs.
The Cree website doesn't mention them either.
The nearest is the XR-C red LED @ 70 lumens, but that isn't a P4 bin.
I'm not convinced the KD version is a better buy, it's dearer and the specification is somewhat suspect...

PDXSteve: so did you take delivery of the red led light? If so, what's your opinion?
Here's a thread on Candlepowerforums that has a beam shot of a red led flashlight:

Quite bright I would say. Brighter than a Dinotte tail light even?

ok, I think I figured it out.
method 1: use a minoura space/swing grip so you get a horizontal bar to use a regular mount to it.

method 2: use a rubber O-ring instead of a hairband, obviously, brown band to illustrate where it goes. might need a spacer or two to get the angle right since saddle bags compress. Depends on how your saddle bag is constructed too, so make sure the O-ring is inside the Velcro loops.
under:


over:


you can also cut off one side of a DX 12000 mount to thread it into the velcro loop your saddle bag has.
or instead of using spacers, chop a DX 12000 in half and use that to give some proper cradled support to your light so it won't slide around badly.

blinky lights are what you want
If your light doesn't blink, you blend in with the surroundings. The blinky aspect makes you stand out and that's the whole reason for a light. This is not an opinion, it's fact. If your tail light doesn't blink, it's not as good, period. Get a Planet Bike SuperfFash. It's all you need. If you want more, get 2. You will get nothing better, you can get brighter, but not better.
