Could be a chip of alu under the ledboard preventing good thermal contact with the body. Or one of the holes in the ledboard shelve that has a protruding edge.
Depending on your mood or skills you could
1)contact Banggood about it, or
2)open the head, unsolder the ledboard and have a look at what is wrong. Then assemble the proper way.
Ordered Grey XHP50.2 5700K
Thanks.
Thanks freeme, order placed. Hope it ships before Feb. 23rd.
What battery gives the longest run time and can handle the XHP50.2 amp draw. I don’t need every last lumen.
And ordered 
Just get the highest capacity ones and avoid turbo. High (the highest ramping mode) is still plenty bright.
That used to be the Shockli 5500 but I think it has been discontinued? How many amps is turbo with the xhp50.2 in the EA01?
Hi,
Can I have a code please?
Thank you
Please send me code.
Thank you
I just noticed that the Mateminco MT04 is now available in quad SST20. No specs that I can find.
5500mAh ones from Vapcell were also great - gone as well. For some reason ~5500mAh 26650 cells disappeared from the market.
It pulls about 15A with XHP.50 (which falls off a cliff right after startup). 3500lm rating is quite conservative, with good cells people are getting over 4500lm. High mode (max ramping mode) is around 2000lm. None of them are sustained - after about 5 minutes output stabilizes at around 600 lumens.
I think 26650 has taken second fiddle to 21700. I was hoping to get at least 1000 sustained after step down. Think that is doable if I start at a lower max ramp to prevent initial heat of turbo?
I don’t think so, when both turbo (~4500lm) and high (~2000lm) stabilize at about 600lm it looks like that’s how it is by design and therefore it should apply to all modes above 600lm.
OK thanks. I will play with the thermal settings when it arrives and hope for better. It seems to have enough mass for better than 600.
I couldn’t wait and ordered it from Mateminco (AE Store). Will it be the same in the package next to the lamp as it is with Astrolux?
What's the hurry? 
Thanks for the code, got one in blue SST40 5K.
From the summer, customs rules will change in my country (maybe all over the EU). I have to buy until then and I will have birthday in a month anyway. :partying_face:
I know this is late, but In my experience messenger with customer service is fantastic help through BG. They have helped me numerous times through the messenger function. Both before and after sale.
Is there supposed to be a set ship date on these I didn’t catch. The listing says in stock, ships in 24 hours. Are group sales items different? Mine has been processing for 3 days.
