CLOSED groupbuy: Wuben A21 (June 10 to 27 2018)

Interested to know how long Turbo mode lasts before it steps down. Hope it’s not like Emisar D4 that starts dropping almost immediately.

I did it too

@M4DM4X, yes I did put my choice. NW XHP70.2

Also, ask Wuben if they are willing to use a 4000k 80CRI XHP70.2

Would make for a dope light.

@Pete, I doubt that it would step down as quickly. It is using a more efficient LED array(4x XP L2s vs 4x Nichia 219Cs), a boost converter, and isn’t overdriving the emitters to their limit, unlike the 219Cs.

It also has a bigger body, meaning it could hold the heat for much longer.

The fact that they claim 4200 lm output leads me to believe that it’s XHP70.2. The XHP70 is only rated at 4022 lm, unless maybe if you overdrive it, which I hope Wuben will not do.

It would be nice for someone to confirm.

I love the “Scenarios” on Wuben’s page. Good to know I can use this light to defend myself from burglar ninjas.

Interested CW XHP70.2

Now on bangood Wuben
Emitter is XHP70

Some pictures show 70 and some show 70.2. I wonder if they are still deciding.

I built a light using a xhp70 and a small OP reflector and still get a bit of a donut shaped hot spot. I hope they go 70.2 like their competitors.

NW xhp70.2 will be available very limited in my groupbuy only

details will soon be sent to the people who entered the list

What about the CW one: will it be XHP 70.2 or 70?

Sounds mouthwatering! I’m on your list for the NW XHP70.2 :wink:

Interested

I chatted with a sales assistant at Wuben and it will be the XHP70.2. I have owned a few Wuben lights and two of the XHP70 models had the XHP70.2 emitter. I won’t expect anything less from Wuben.

CW will also be xhp70.2 of course

I don’t see why they think this should be priced $30 higher than the T102. Hopefully the GB price will be more reasonable.

interested

L30 on the same bangood for 10$ cheaper

I’m actually looking forward to this light in 70.2 and NW, I’m in for sure.

Wish the o-ring seal was red instead of yellow in the middle of the light…oh well

Are they pairing this light with a 4800 mAh 21700 battery? I’m not sure that battery is capable of delivering 4200 lumen.

Is this a rewrapped Samsung 48G?

With a fully charged battery, it will need to pull about 13A to 14A to deliver 4200 lumen and the 48G is only rated at about 8A to 10A continous.

At lower voltages the amp draw will increase.

Since turbo is not considered continous, maybe they can get away with it?

Yeah I didn’t think of that. As far as I know it’s the 4000mah cells that can handle higher continuous current draw, like 20A and higher. Maybe there’s another new type of 4800mah cell on the market? I would like to see how the first reviews look regarding the current draw.
