638T-500-F-W 700mW 638nm Red Laser Pointer Review

In this video you gonna see a Very Powerful Red Orange Laser that I buy from Aliexpress a few weeks ago and I promise that I will make a video of this product.

The laser is called: 638T-500-F-W, is a Class IV (4) 700mW with a wavelength (nm) of 638nm (red-orange) color that is much more visible than the 650nm red lasers.
The laser is from China and it took 22 days to arrive in Chile, the package and its contents are intact, it was a good service.

The laser is very Bright! (recommended to use safety glasses), and is very good to burn, the only bad thing is the dot divergence that is not the best but not very bad, with a good fit it can be used over long-short distances or to burn.
The divergence of this laser can be improved a lot with good lens, I tried it with other lenses and the results were better.

Personal Opinion:
The laser is very awesome and good, incredible visibility but a not good divergence, its visibility is so much for a red laser that can be compared with a 100mW 532nm green laser or a 1500mW 450nm blue laser that I will show later in the video.

My rating:
Design: 9.5/10, (is much better and a better finish than the model 900 laser.
it's a not a very big laser, is 16cm long, but high power.
Power: 9.5/10 (is very close to the Wicked Lasers Inferno of ~820mW)
Visibility: 9.2/10 (for a red laser is incredibly visible but if it weren't for the slightly bad divergence, this would be better)
Dot Divergence: 4.9/10 (rectangular at long distances)
My Final Rating: 8.5/10

Battery Required and Direction:
Required 1x18650 (no flat top)
Direction: Positive '+' to tail top and the Negative '-' to spring.
I recommend using a +2500mAh 18650 battery to have more duration and power time.

Diode: Oclaro HL63193MG
Working Time: ~45 seconds on, ~15 seconds off
