Review: Inexpensive Red Lasers Work Great - I bought these to illuminate a dot on the dashboard of cars parked in my garage. Way better than a tennis ball and string! The lasers have a well defined and focused dot. A couple of the lasers were lower in brightness, but not bad considering the price. Laser diodes are designed to be operated at a specific current. In this case, I estimate 20 mA is about right. The diodes have a 91 ohm resistor in series, so the correct current is obtained by using a 5 volt power supply. Some careful soldering would allow you to bypass the series resistor. The case is made of brass and unscrews at the center once you break free the glue keeping it from turning. The lens is spring loaded against the objective end. The rear end contains the laser diode mounted to a brass heatsink and a PCB containing the + lead and the 91 ohm resistor. The negative lead is attached to a PCB that pushes against the brass heatsink when assembled. Not sure about the lifetime of the laser diode. Lower currents mean longer life. My car park device is on 24/7 so we''ll see. For the fun of it, I took some microphotographs of the diode. The diode itself is way small. In one photo you can see a 0.7 pencil lead. I'm definitely getting my money's worth out of these lasers!
Review: Wonderful for Projects - Previously, I was using the lasers, where were mounted on the circuit board. Fortunately, the project I was working on only needed to have the receiver send a signal the sensor had irradiation or not. This allowed me to used the laser strictly for the beam and reduce the cost tremendously. I found a metal bracket on desertcart that fit the 6mm size perfectly. If you need lasers for a project (school, home escape room, or other needs), I would recommend these lasers. Not one has failed.

### ⭐⭐⭐⭐⭐ Good lasers. Low cost. Fragile wires
*by M***M on October 7, 2023*

These are very good lasers. The output is elliptical (maybe 1.5:1) but largely uniform within the beam. Turning the barrel gives a wide range of focus adjustment. The wires are small gauge, so it's easy (for students, anyway) to break the wires off, but they're so inexpensive that replacement isn't heartbreaking. With a 5V input, the lasers are nice and bright.
