4.5a driver?

I would stay under 4.0 amps for a NUBM07E, mine runs at 3.5 amps and it looks great and makes good power, more than that you may shorten it's life.

You can run yours past 3.5 amps if you want, but I don't think it's worth it unless you don't mind buying a new one if it pops.

Here's an 07E running at 3.5 amps with a 25mm zoom lens.

Here it is with a 3 element lens at 3.5 amps.

Hi Redcowboy, mate how far away from the laser is the box your burning and we're can I get that lens!

It was 7 feet plus a couple inches but I have lit boxes out my window at 12 feet with it but it clips the wide axis like the 3 element lens does.
It's a scavenged projection TV optic.
You could probably do better with a G7 and 3X expander from podo's shop.

The 25mm lens I use clips some of the highly divergent axis, but it still extends burning range, I talked about it in the thread below.

Hi i have it at 4.5A NUBM07E and i have another at 3.5A i only did it for testing purposes at 4.5A i recommend not to go above 4A its because it will drain your battery faster and you could shorten the life i only did it in case it goes bad i can always get more diode's if you have the money go for it its just not recommended, stay at 3.5A
