The Laser Devices system is a much more robust package in terms of light output and durability.
The shock isolation and beam quality is at a higher level. Laser will hold zero.
Remote switches are available.
See Spec Sheet:
www.laserdevices.com/pdf/210033C_5.pdfThe Streamlight/Insight Light is smaller package, and the toggle switching is easier to access/activate. I will put it much lower on the durability scale (both light and laser). I do know of several departments that have returned this system because they had difficulties with laser holding zero. This problem may have been rectified, but I am not aware of any specific upgrade to fix. Maybe somebody else does. Remote switches are available that will activate the Light Only.
I also regularly end up with M3/M6's in my hand during weapon retention drilling against someone who has the Insight light on their weapon.
Overall, if I had the choice for a Laser/Light combo, I would select the LD system.
We offer both packages through our webstore.
