Hello, I bought a diode with driver from DTR and measured the power consumption. It showed 10w for a 2.7w diode. The diode is a NDB7875 445nm and the driver is a Super X-Driver/1.6A-2.4A/6V-9V 2A+. Is it supposed to be that inefficient? Does it supposed to have thermal paste going to it as 7w is...

Yes. It just arrived today. I tried it with my cheap blue 405nm ebay pointer. Is it supposed to have a white dot?

Okay, I should be able to practice using it at 500mw.

Hello VLC18, It's for burning only, not for the sky as there are a lot of planes flying by. I bought a diode with the driver but it's not portable so I am planning to use it with a lab bench. Is it bad if I use the cc on my lab bench to lower the power? I will try lowering power first to 500mw...

Okay, Is DTR's Laser Shop a place to buy the diode with cc board? I'm planning to get the NDB7875 with driver and heatsink. Is this an OK choice. I'm going to power it using a lab bench. Do you know where to get Eagle Pair? SurvivalLaserUSA shows no stock.

Hello, I am in the US and my budget is 180USD. Thank you I will get the Eagle Pair. I am going to use it to burn, and sometimes to point at stars.

Hello, I am new to lasers. I know laser safety (general) I need a place to buy these laser power meter safety glasses for blue lasers 1-3 W laser (for burning) Batteries for the laser
