Pro RGB Laser Module for Laser Projectors and Show Systems
The SM20 is a pro RGB laser module for laser projectors, custom projector builds, and professional laser show system integration. It works well for OEM builds, replacement upgrades, and projector assembly projects that need a dependable laser module with stable output. This unit is suitable for a laser show projector, a programmable laser projector, or a dedicated show laser system, while its structure supports easier installation in common projector housings. For buyers seeking a professional laser projector light source rather than a consumer toy projector, the SM20 is a more serious solution.
True RGB Wavelengths for Clean Color Mixing
RGB Output: The SM20 uses a true RGB wavelength set of 638±5nm red, 525±5nm green, and 450±5nm blue for vivid mixed-color projection.
Color Separation: This wavelength combination helps deliver better color separation for graphics, logos, beam effects, and projection work where image readability matters.
Power Distribution: The 20W configuration is listed at about 5.6W red, 6W green, and 8.5W blue, giving the module balanced output for projection use.
Show Use: For a show laser or projector system that needs vivid color performance, this setup provides a stronger foundation than lower-grade mixed modules.
Commercial Relevance: This makes the SM20 a strong fit for buyers searching for an rgb laser light source for projector builds rather than a finished consumer fixture.
All-Fiber Shaping for Better Beam Quality
Beam Profile: The SM20 uses all-fiber shaping, which helps produce a cleaner beam profile and more controlled spot quality.
Projection Clarity: That cleaner output helps patterns, text, graphics, and logos look sharper in projection and scanning applications.
Divergence Control: The module is rated at 1.0 mrad divergence, which supports more predictable throw performance in professional projection work.
Beam Size Data: It is specified at about 18 × 20 mm at 10m and 30 × 28 mm at 20m, which is useful for graphics and long-throw planning.
Use Case Fit: That makes this laser module especially suitable for laser projectors, mapping systems, logo projection, and other installs where beam quality matters.
Fast Analog Modulation for Show Control
Control Method: The SM20 supports analog modulation, making it easier to integrate into a professional laser show system or custom projector control chain
Voltage Logic: The module is described as providing full power above 2V, laser off below 2V, with an approximate working range of 0.12V–4.95V.
Programming Value: This predictable response helps brightness fades, dimming behavior, and programmed transitions stay more consistent from setup to showtime.
System Integration: For integrators building a programmable laser projector, this kind of analog behavior is easier to work into standard show workflows.
Professional Advantage: It is a practical choice for buyers looking for a reliable show laser source rather than a basic unmanaged light engine.
Compact Footprint and Stable Thermal Design
Compact Size: The module size is approximately 220 × 147 × 50.5 mm, with a light output height of 40 mm, which helps with enclosure planning.
Cooling Structure: The product page lists heatsink + TEC cooling + cast aluminum housing + bottom fans for stable operation.
Warm-Up Time: The uploaded 20W file lists a preheat time under 1 minute, which helps improve setup efficiency.
Operating Range: The working temperature is listed at -30°C to 40°C, though the module should still be used in a dry, clean, low-vibration environment.
Installation Guidance: For better long-term stability, enclosure airflow should follow the module’s heat path during integration.

Good product-May need to troubleshoot
I am giving this product five stars even though I had issues resetting my printer because it was not product fault. The maintenance box was easy to install. Based on other reviews, I was prepared for the wic reset site that looked suspicious. I will say it is legit. I purchased a reset key which I later found out that I did not need. Read further and I will explain.
After I downloaded the WIC software, I spent over 2 hours troubleshooting yrying to reset my printer. I am writing this hoping that it might help others. In the end, the problem was my Wi-Fi was not recognizing the printer. When I was trying to reset it. I ended up connecting my printer via USB cable and I was immediately able to reset my printer and start printing again. I am going to list the troubleshooting steps I took, but you might want to try that first. In addition, before purchasing a reset key, they do offer a trial key. If you have never used a trial on that printer. I suggest doing this first because in the end I used the trial rather than the key that I had purchased.
Here are a few additional troubleshooting steps you could try:
1. Ensure Correct Reset Key: Double-check that the reset key you purchased is for the correct model of your printer. If it's specific to another model or region, it may not work correctly.
2. Reinstall WIC Software: Uninstall and reinstall the WIC software to make sure it's functioning properly. Sometimes a corrupted installation can cause errors.
3. Run the Software as Administrator: Make sure you are running the WIC software as an administrator. Right-click on the WIC Reset tool icon and choose "Run as Administrator."
4. Disable Firewall/Antivirus Temporarily: Your firewall or antivirus software may be interfering with the connection. Temporarily disable them and try again to see if that helps. Make sure to turn it back on when finished.
5. Try a Different USB Port: If you are connecting via USB, try switching to another port. Alternatively, if you're using Wi-Fi, you might want to try a USB connection to see if that helps the software communicate with the printer. This is what worked for me.
6. Use a Different Computer: If possible, try using the reset software and key on a different computer. Sometimes system-specific issues can interfere with communication between the software and the printer.
7. Check for Firmware Updates: Ensure that your printer's firmware is up to date. If it's outdated, it might cause incompatibility with the reset tool. Be cautious, as some updates can prevent third-party reset tools from working.
If none of the above works, it might be worth contacting the vendor of the reset key. They may have specific guidance or offer a replacement key if the one you purchased is faulty.
Last resort would probably be to call Epson.

Perfect for my Epson 2720!
When my Epson 2720 printer pooped out on me and said my ink waste box was full, I was so sad. After watching a billion YouTube videos, I learned there are a ton of people selling new ink boxes and I had no clue which one to pick.
I am the most electronically illiterate person on the planet so I just knew it wouldn't be easy for me to fix... wrong! This kit came with the new ink waste box, tools to change it out, a bag to throw the ink filled box into, instructions, and an extra pad for next time.
After removing the old box, the new one slid in perfectly. Resetting the wic code was extremely easy as well! The instructions show step by step diagrams on what to do. It was a fast and simple process.
It all worked out too well for me (normally it's a domino effect of chaos when I repair something) so the first print to see if it all worked was a nail biter. It printed beautifully!
If you have a 2720 that needs repaired, this is the product for you!

Great replacement waste ink pad!
This waste ink pad maintenance box works well as a replacement for my printer. It was easy to install and fits perfectly. The extra sponge is a nice bonus and helps absorb excess ink effectively. The packaging was secure and arrived in good condition.
My only small complaint is that it didn’t come with clear instructions, so I had to search online to be sure I was installing it correctly. Other than that, it does the job and is a cost-effective alternative to the original brand.
Would definitely recommend if you’re looking for a reliable maintenance box!

MAC OS users read this
1. There is no way around needing to reset the waste ink counter by downloading software, unless you want to pay for Epson to fix your printer. Replacing the waste ink tank alone will not make your printer work. Most of the WIC software you'll find if you google search this issue is only for WINDOWS.
2. The software recommendation that came with this part was for WINDOWS users only. It's an .exe file. I researched and found one that's for MAC, and LINUX (as well as windows.) I had to read the FAQ on that site to learn how to tell my MAC I was willing to bypass security and install it, but this was simple, and I was even able to use a trial key instead of paying. The trial key reset the counter to 80% so I'll need to go through the process again sooner than if I'd paid, but I was pleased to find out it would work first before buying a key. The site was "my printer club."
3. I have zero affiliation with "my printer club." Just trying to help out MAC users who may think they're out of luck, as it even says on the Epson site, direct quote: "Yes, the service alert and service repair process may be temporarily delayed on most printers by using the Maintenance Reset Utility to enable printing for a short period of time. This method is available to Windows users (Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP) as a one-time option while customers determine the best next steps for repairs. Currently there is no Maintenance Reset Utility available to Mac OS users."
4. Installing the waste tank purchased here was quick and easy. I'm only giving 4 stars because I had no idea when I bought it that their instructions weren't for MAC.
