Designed for professionals with basic electrical skills, it offers superior heat management and fine focus capabilities, making it ideal for detailed laser applications. Safety and proper operation are critical, as this powerful diode demands a constant current driver and protective eyewear. ## Description This listing is for ONE Brand New Nichia NUBM44/47 450nm 7-Watt 9mm Laser Diode Mounted in 12mm x 30mm Metal Housing Module w/ G-2 Glass Lens and 22AWG Silicone Leads. Improved Module Design - Solid core back half of module for increased heat dissipation. Please Note: Basic electrical knowledge and skills are required for setup and operation of this device. This product may not be suitable for everyone. Reverse polarity, excessive current and high heat will damage or ruin these. A proper CONSTANT CURRENT laser diode driver is required to drive the diode. The current should not exceed 4.5 amps. Because the NUBM44 laser diode is a multi-mode diode you will always get a rectangle as opposed to a dot. This is a characteristic of all multi-mode laser diodes. The closer you can get the lens to the work the smaller that rectangle will become and the finer the detail you can achieve. You want to focus it so you have the cleanest and thinnest line possible. Don't try to make it symmetrical or you will produce a larger and less powerful beam. Be aware that the closer you get it to the work the more likely you are to get smoke and/or soot on the lens. A secondary air assist fan will greatly help reduce that risk. If you do get smoke on the lens the beam will start to look blurry. It can be cleaned with a very soft lens cloth and some 91% rubbing alcohol. This is a very powerful device and you must never shine it at another person, animal, aircraft or another persons property. This is NOT a toy! You are solely responsible for it's use. Always wear protective eyewear that is rated to block the 400-470nm wavelength and NEVER look directly at the beam. You only have one set of eyes! Due to the volatile nature of electronics of this type, returns will only be accepted in original, sealed packaging. ## Features - 7 Watt Laser Diode w/ G-2 Lens ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07P8L792J | | Best Sellers Rank | #807,490 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #233 in Diode Lasers | | Date First Available | March 3, 2019 | | Manufacturer | Barnett Unlimited | ## Images ![7W ~ Nichia NUBM44 450nm Laser DIODE in Module w/G-2 Lens & Leads - Image 1](https://m.media-amazon.com/images/I/71WIwY0mDAL.jpg) ![7W ~ Nichia NUBM44 450nm Laser DIODE in Module w/G-2 Lens & Leads - Image 2](https://m.media-amazon.com/images/I/71QiTBY2bgL.jpg) ![7W ~ Nichia NUBM44 450nm Laser DIODE in Module w/G-2 Lens & Leads - Image 3](https://m.media-amazon.com/images/I/616918ZpPHL.jpg) ## Questions & Answers **Q: Is 7W the power consumption or the light output? I assume this is more like 1.5w output?** A: The optical output exceeds 7 watts at 4.5 amps driving current. This is the highest output visible light laser diode available. **Q: Is the red cable Anode and black cable cathode?** A: Yes. **Q: Where is the logic input that I can use to control the on/off** A: The laser module requires a constant current driver. You can not connect the laser directly to a power supply. You will control the driver. ## Frequently Bought Together - 7W ~ Nichia NUBM44 450nm Laser DIODE in Module w/G-2 Lens & Leads - HiLetgo 10pcs 5V 650nm 5mW Red Dot Laser Head Red Laser Diode Laser Tube with Leads Head Outer Diameter 6mm - ALLECIN SN74HC595N 8-Bit Shift Registers with 3-State Output Registers DIP-16 SN74HC595 74HC595 Shift Register (Pack of 30pcs) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/112157472-7w-nichia-nubm44-450nm-laser-diode-in-module-w-g](https://www.desertcart.tn/products/112157472-7w-nichia-nubm44-450nm-laser-diode-in-module-w-g) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-11*
