Review on CEC XPR19 P13 5S T 3 25: High-Quality Replacement Bulb by Vanessa Harrison

You get what you pay for. These bulbs are sold in bulk because you will be replacing them regularly. The price is right, but life is short. They are bright when they work. The original bulb and replacement that came with the flashlight I used lasted about 8 years. These final months depend on the amount of usage they receive. Quality replacements don't seem like an option, so these are cheap disposables.
