Default Need a labby with good duty cycle

Hello LPF,

Until Now i have seen and used handhelds and now i want a laser which has some decent duty cycle which can run for few hours together.
I know labby's have decent amount of duty cycle but don't know how long and what are the different labby's i can get. I have read about TEC and stuff but it would be better if you guys tell, What all kind of labby's we do have and which has the best duty cycle. If so, can we cool down the labby further with heatsinking and adding coolers and stuff?

I want somewhere around 150mw to 200mw 532nm, 405 or 445nm to run for 3 to 4 hours without turning off for cooling.

Virtually any lab unit that plugs into the wall will run as long as you want. Just pick one.

Do you happen to know any good labby sellers. I have seen most of the DIY Labby's built by LFP members do not have a box with then. I think they are called modulators/modulation. What is the use of those modulation boxes, and can we order a labby without one of those?

Those "modulation boxes" as you call them are the driver and power supply for the laser. Typically the laser head is just the diode, fan and TEC which needs to be driven by the power supply + driver.

Some units have it all built into the head of the laser, but it's much more common to get separate head/PSU units.

We can help you better if you actually tell us what you need the laser to do... For what will you be using it?
