Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers find the laser diodes work well and offer good value for money, with one customer noting they perform well at 4.5V. They are bright, with one review mentioning stable color and intensity over time, and customers find them easy to use and install, particularly suitable for circuit building. The build quality and focusability receive mixed feedback - while some praise the solid beam, others find them not well focused, and while some appreciate the small size, others note the short leads.

Laser Beam Combiner Red Dot on 80W laser "OMtech"

- Reviewed in the United States on July 26, 2024Bought this to make an automatic laser pointer for my cats. My initial fear of the lights being dim were immediately received when I hooked it up to the Arduino. Great performance. Quality so far seems pretty good, however it seems like the wires are lightly soldered on. So far none of them have broken free. Very tiny, which is great, and probably the best value for the money considering quality and quantity. Love them!
- Reviewed in the United States on September 21, 2020The media could not be loaded.
They only require a 5-volt power supply, that's it. I used an old desktop Christmas tree power/controller to power the diode, it Powers the diode quite nicely at 4.5 volts, and using the controller I get different beam options, (video attached) remember no driver boards or power modules needed, use batteries, 5 volt power supplies, (the diode will work at 3-5 volts although at 3v it's not that bright)
THEY ARE FOCUSABLE ! I have seen complaints that they are out of focus, that's because the barrel of the diode is threaded, you can screw the forward portion of the diode barrel in and out to focus it at different distances, it is not one solid piece of brass but split in the middle.
This is my second purchase of these, all have worked flawlessly and consistently.
One caveat, the wiring is thin, as others have stated, they will break off at the solder joint quite easily. My suggestion cut down some electrical tape and wrap it around the board and wires to act as a strain relief, or, encapsulate the the board and wires with hot glue, this is the best way.
Although not tested, my 40 years experience in lasers tells me these are hotter than a typical 5 MW laser diode.
- Reviewed in the United States on May 11, 2024I use these in models, and they are great for that use. One or two out of the lot don’t work properly but that’s okay at this price point. Make sure to test before you solder. The lens is adjustable and you can rotate till you have a nice sharp point of light. These have been great.
- Reviewed in the United States on June 16, 2024These LASERS work perfect, are really bright and the cost is outstanding. Super Deal...
- Reviewed in the United States on May 15, 2024Can’t beat these lasers for the price. I power them with a 3 AA battery box with built in switch. Secure wires with a blob of hot glue for a stress relief. I mounted one in a hole drilled in wood and accidentally pulled the ground wire (blue) loose. No problem, I just stripped the wire and pinched it between the Brass housing and the side of the hole and it still works fine. I wish the body was 1/4” diameter, think it’s metric. Wish I had a few 40 years ago.
- Reviewed in the United States on April 19, 2025Quality laser diodes. Operates directly from 5 volts... coolly,
Expected lower quality, due to the low price, but
was impressed with the quality of the product, and
was further impressed that there was more than one
at this price level.
- Reviewed in the United States on April 22, 2024The media could not be loaded.
- Reviewed in the United States on November 28, 2022I needed a few laser diodes for some projects I'm working on. These mini lasers fit the bill. They work great and are relatively inexpensive. The working voltage is 5v. I tried using 3.3v and it works but the laser light is dimmed.
The wires are on the thin side so you might need to solder on a thicker gauge. It’s easy to do just remember the polarity matters.
