    Ituo WIZ XP2 1500 Lumen Mountain Bike Light

    Yes guys, here it is, the Ituo WIZ XP2!!!

    We spoke, Ituo listened. Other lights have some catching up to do.

    https://www.ituolights.com/collectio...bike-light-kit



    Will be in stock (including US) mid-late June.

    Ok here's the details:

    It's really nice quality, very much in line with what we see from Ituo. But I think this one is a tad better. Very clean look.

    -Dual Cree XM-L2 U3 Neutral White emitters.
    - rated at 1500lumens, 1559 actual @ 30 seconds
    -removable wired remote
    -uses same optics as wiz20 so easily available and changeable to any pattern you want.
    - fins are cut to proper depth on the front half, back half of the sides is cut really deep to increase thermal behidn emitters and @ driver
    -gopro mount is STANDARD. Works like the WIZ1 and WIZ2 mount. QR slide lock gopro adapter then their QR style gopro handlebar mount.
    -top button with standard 2 color battery level indication (but not very bright which is good)
    -fully programmable driver. Hidden flash modes, press and hold for off, etc
    - 18awg battery cable (yes your reading that right!)
    -weight: 88g 
    -includes a good gopro style helmet mount that uses Velcro straps (forgot a pic will do that tonight)
    -run time is 3hrs on Ituo battery pack. Pack is 8.4v 4 x NCR18650Bf 3350mah Panasonic cells. Total 6700mah capacity, full protection circuit, neoprene pouch.





    Now here's a wrench in the mix. They used the threaded style connectors. BUT DONT LOOSE FAITH JUST YET:

    I decided to test it with a normal MS connector. Ok it plugs in. Now the NUT is rather large. Largest I've ever seen in this application. So I decided to try and thread it onto a MS style female connector and...

    IT WORKS AND HOLDS NICELY. Plenty secure. SO YOU CAN USE YOUR OWN PACKS THAT USE MS STYLE CONNECTORS. Does take a bit of effort the first time threading the nut over a MS connector but it DOES NOT damage anything. And works perfectly. Also since there is an oring on the connector, it seals just fine into the MS style connector.

    Summary, the light head only is very much an option as long as you have ROUND MS style connectors on your existing battery pack.

    Picture of Ituo connector on ms style:


    Here is the last " first impression " thing I had to post:

    All lights we see producing anywhere close to these lumens (even X2 and Duo) have a current draw OVER 2A. The XP2....1.8-1.9A current draw on high (1559 lumens). Only drivers I know that can do that are my custom prototypes from Mtnelectronics and the taskled drivers. Ituo did a "one up" on the other brands, they increased driver efficiency by a substantial percentage!!! Didn't expect that.

    Only gripe I have is the button on the remote is almost flush. I did let them know to use a bigger silicone button so it's easy to feel through gloves.

    Update:

    Thermal protection details: FULL, RAPIDLY RESPONDING, ACTIVE THERMAL MANAGEMENT! Does have a "hard" step down with no air flow if temp continues to increase beyond the active control. Drops to 50% (about 800 lumens) but I kick the fan on and within 3-4 seconds output rapidly starts climbing again. During active control it's litterally 1 second before lux readings start increasing when I turn the fan on.

    Thermally stable on the sphere system (which airflow isn't great, just even around the entire head).



    Beam Shots (sorry the medium one looked like crap, i must have moved when trying to take the picture)
