I’ve seen advertised led lasers that claim are equivalent to a 50 watt co2… the input power to these are 40watts, so there is no way it’s generating addition power. The led people can use misleading advertising to sell the product. Led lasers are generally specified by their ‘input’ power and the co2, by it’s output power. You can’t directly compare an led with a co2, there is a frequency difference in the generated ‘beam’ between them. You can improve a K40 and run Lightburn with a < $50 upgrade board. The controller on board is quite a creation, but the software that runs it does all the work.

Is it hobby/learning and what materials do you want to use? That is the most important part of purchasing any kind of machine. You were not clear on the intended purpose for the machine.
