Same features as full sized tactical lights without the weight and bulk - Crimson Trace Lightguard Springfield Full-Size XDM XD Gun Light

This has enough output to illuminate any indoor environment. If you need more light than that because you are using a handgun at night time outdoors like cops do then go for a full sized light. But for the priciest a great addition to any home defense weapon.
Pros: Low profile light suitable for concealed carry
Cons: Few holster options
