Heavy duty tool
The beautiful color options like Dark Green and Sand give this heavy-duty tactical light a fantastic look. I love the quad-core LED setup that pushes out an intense amount of lumens to easily light up a large field. It balances beautifully in the hand, combining aesthetics with brute performance.

Acebeam Defender P17: The Professional’s Powerhouse
The Defender P17 is the heavy-hitting big brother of the P-series, trading the slimness of the P16 for sheer, brute force. Utilizing the Cree XHP70.3 HI LED, it blasts out 4,900 lumens with a massive, high-intensity beam that reaches 445 meters. For enthusiasts, it’s all about that sustained performance; the larger head and deep cooling fins allow it to hold high outputs longer than almost anything in its class.

The dual-switch tail cap feels incredibly rugged, offering instant access to strobe or turbo with a satisfyingly heavy mechanical click. It feels balanced and authoritative in the hand, making it the perfect "duty-style" light for those who want maximum brightness without sacrificing a clean, throwy beam profile.

Tactical use
Acebeam’s tactical switches are one of the big reasons their lights feel so good in real use. The dual‑tail layouts on models like the Defender series give instant access to turbo and strobe without having to think about mode memory or side switches, which is exactly what you want under stress

P17 with XHP 70.3 HI
I love it - I got the green version and the beam that the XHP 70.3 HI creates is just beautiful. It's my favourite LED in a really compact format.
The torch itself is built like a tank, has 3 UI modes and dual tail switches, that are a joy to operate.
I only wished, there was an instant Turbo in tactical mode, not just high :)
Output is just perfect, it holds Turbo and high for a really long time and has enough throw + flood to be used as an all round light / EDC.
Would also have loved a holster :)
