Just a prelim test at 6 volts (minimum seems to be 2.2v to turn on) it burned my black mouse pad. I'm not a pro on this stuff but I've never had a 5mW laser able to burn things 12 inches away, but I'm happy with extra power but just be careful this is way more than a typical 5mW laser pointer, WEAR EYE PROTECTION I pointed it at something dark 30 feet away and had to peak over my glasses and it was pretty frickin' bright. Review: Defective and replacement was also defective - I had bad luck with blue lasers from this seller. I ordered a blue line laser and a blue dot laser. The line laser is very bright, as it should be. The dot laser in comparison is very dim. I returned the blue dot laser for a replacement, but the replacement was likewise very dim. A properly functioning dot laser should be just as bright as a line laser - the internal components are the same. I would be very pleased to purchase a properly working blue dot laser from this seller, and would order again if I thought this was just an isolated incident. But I've now been through the cycle of receiving a defective product, requesting a replacement, and being provided yet another defective product. I am concerned that they have failed to do adequate quality control on their stock, and I don't want to spend time ordering and returning again and again until I finally receive one that works properly. This is disappointing, and also somewhat confusing, as I have also ordered red and green dot and line lasers from this seller and all of them work properly. I will update if the seller offers me a solution. ## Features - Focusable 445nm 5mw violet laser module - If laser spot is not dot when you get,pls adjust the front cap to get dot as you need at different distance - Blue lazer Diode - Blue Dot laser diode ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BV9T9MXY | | Best Sellers Rank | #243,140 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #40 in Diode Lasers | | Brand | Qiaoba | | Brand Name | Qiaoba | | Color | Blue | | Customer Reviews | 3.7 out of 5 stars 36 Reviews | | Included Components | laser module | | Item Type Name | 445nm | | Level Measurement Type | laser | | Manufacturer | Qiaoba | | Manufacturer Part Number | 631514772536 | | Material | Glass LENS | | Material Type | Glass LENS | | Model Number | BM5 | | Operation Mode | Automatic | | Style | Laser | | Style Name | Laser | | Unit Count | 1 Count | ## Product Details - **Brand:** Qiaoba - **Color:** Blue - **Material:** Glass LENS - **Operation Mode:** Automatic - **Style:** Laser ## Images ![450nm Blue Module Diode (Industrial Blue Dot)445nm - Image 1](https://m.media-amazon.com/images/I/41ojTqTV9rL.jpg) ![450nm Blue Module Diode (Industrial Blue Dot)445nm - Image 2](https://m.media-amazon.com/images/I/31JQmUPEgFL.jpg) ![450nm Blue Module Diode (Industrial Blue Dot)445nm - Image 3](https://m.media-amazon.com/images/I/21J03XZbqVL.jpg) ![450nm Blue Module Diode (Industrial Blue Dot)445nm - Image 4](https://m.media-amazon.com/images/I/4127krIjIqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by A***R on April 16, 2024* Seems to work great.

Burns too! *by J***9 on June 4, 2023* Ok- First let me say I'm a novice to diode lasers- burned my fair share of DVD diodes, built numerous working drivers for the diodes, but I still have A LOT to learn about & from diode lasers! That being said- my experience w/this diode goes as such; received laser diode in good time (2 days), figured out that it has a driver built outside the metal housing, & encased in (hotglue?) & shrinktubing, has a glass lenses, will lase @ 7.5volts via wall transformer, a very COOL Blue, NOT Violet, beam! Doesn't burn at this voltage: well- it WILL burn retinas, moist, valuable, & super important unprotected eyeballs... And no, I didn't burn mine- cause I like my vision & took other enthusiasts advice to wear the correct protective eyewear! Thank you for that- cause this laser is BEAUTIFUL, but only takes one careless moment or lapse of attention & it's a permanent regret! So, be as smart as it takes to build & use these things to protect yourself and others! Ok- I wanted to burn stuff, & 7.5v's wasn't showing any substantial damage I could brag on, so I grabbed a 9volt battery, adjusted the focal length (about 7"-10") and eureka! Smoke!! Damage!! Finally my first sign of destruction-albiet it was 5x smaller than the period at the end of this sentence. Hmm- more power!?!= Bigger damage?!? Yep- more power sure did more damage; the driver was enveloped in a dirty jet-black smoke that stunk & proceeded to have me banned to the outside workbench!! The Wife was Not pleased her beautiful oil diffuser smell-good stuff was rendered ineffective instantly! Lessons learned- So- I'm sure my diode is done- housing & lenses still usable, driver is obviously toast- literally. 12volts was too much for it. So I promptly ordered another module- I am going to receive it here any minute! Now, as you can guess I'm going to pamper this thing till I educate myself on the tolerances the diode can safely withstand- like big heatsinks, proper power supply and cooling fans!! Lol! In all seriousness, this is a great small blue (445nm) burning laser that should be respected & used in a mature manner. Not a pet chasing toy to be sure- but it will be an awesome addition to my 5 color laser paragraph display! I rated it 4 stars cause it should come with at least a little more documentation- however, saying that probably just exposed my ignorance! Be smart- be safe. Yes do buy if it fits your needs. It is worth it!!! ## Frequently Bought Together - Qiaoba Laser Module Blue Diode 450nm (Industrial Blue Laser)445nm - Qiaoba Laser Module Violet Purple Diode 405nm (Industrial DOT Laser)405nm DC3-5V - HiLetgo 10pcs 5V 650nm 5mW Red Dot Laser Head Red Laser Diode Laser Tube with Leads Head Outer Diameter 6mm --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/522388471-450nm-blue-module-diode-industrial-blue-dot-445nm](https://www.desertcart.jp/products/522388471-450nm-blue-module-diode-industrial-blue-dot-445nm) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-05*
