Quick warm-up ensures consistent brightness even in cooler environments.

## Description

Dimensions: 12x38mm( without PCB circuit size) Output Wavelength: 532nm (+-10nm) Laser Shape: Dot/Line Beam Divergency: <1.5mard Shell material: Brass Circuit Control: ACC line Reverse Polarity Protection: Yes Working Voltage: DC 3- 3.7V Working Current: I <250mA Warm-up time: None Operating temperature: 15°C ; ~ +40°C; Storage temperature: -10°C ~ +55°C; Package: 1 x532nm Laser Module Note: 532nm Green Laser is made by 808nm Laser Diode plus Crystal lens to transfer Green Light, it needs preheat 2-5seconds under 10 °C. In lower temperature when Green Light is weak at beginning,after preheat it will turn bright .It is normal.

Review: Exactly what I needed, small , bright, adjustable - Exactly what I was looking for and what was promised. small but bright and the width or "fatness" of the line is adjustable, as you can see in provided images where the module is about 2.5-3 feet or 1m from target. Good value, I was worried that they may not be bright enough for my application at only 5 mW but it may seem to be just fine.
Review: Just what I needed for my Laser Swamp - Coupled with a simple buck converter, these laser modules were perfect for my DIY laser swamp effect. Can't wait to run them longer than an hour outside and see the magic.

### ⭐⭐⭐⭐⭐ Works great with a 3.3v Buck Converter
*by C***. on November 1, 2024*

Added this converter (https://www.amazon.com/dp/B0D3B277BD?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) and an old cell power adapter and these worked perfectly for our haunt. Some 3D printed parts to hold things in place and this proved to be a great budget option for us.
