I wanted a light that could withstand the rigors of everyday use and potential harsh conditions. Many tactical lights are built to be shockproof and water-resistant. I made sure to look for ratings that indicated their capability to handle various environments. Battery Life and Power Source Battery life was another consideration that I took seriously. I wanted a light that would last through extended use. I explored different power sources, including rechargeable and disposable batteries. I ultimately preferred a rechargeable option to minimize ongoing costs and ensure my light would be ready when needed. Price Point and Value Budgeting for a light was essential for my purchase. I found that prices varied widely depending on the brand and features. I aimed to find a light that offered good value without compromising on essential features. It was important for me to balance quality and affordability to ensure I was making a wise investment.
