My Skillhunt H03 should arrive today. And you can get the lamp also with USB charging. But for a 10yr old i would not use Li ion batterys!
If i were you i would chekout Armytek (ARMYTEK OFFERS and PROMOTIONS). You can get a BLF discount and many light are already lowered in price.
But especialy chekout the Tiara A1
It uses 1xAA / 1x14500 Li-Ion and for 17,50$ you get a nice light for a very nice price (https://www.armytek.com/products/flashlights/multi-flashlights/armytek-tiara-a1/)
