Sanwu Silver 1W 638nm Red Laser Pointer Review

Описание: New Laser Pointer review video! on this occasion one of the rarest lasers ever today, a 1W (1000mW) 638nm red, a bright red color that makes its visibility greater than the 650nm that we see everywhere.

Info & Opinion:
Laser is from Sanwu Silver Series bought from laserpointerstore.com secure shopping site at $240 USD, the price is a nightmare but I couldn't find anything better, the laser has different batteries settings, a super good driver that regulates consumption and power, solid body and the thread of the collimator lens protected by another thread with a glass circle.
Laser turns on with ~1second of delay because have a soft start caused by driver, It doesn't bother me at all.
Visibility is greater than a 100mW 532nm green but inferior to 450nm 1W blue but the dot is brighter.

My rating:
Design: 9.7/10 (good on every aspect except for the small problem on switch tailcap for 18350s)
Power: 9.7/10 (very controlled, no overbost or pulse type)
Visibility: 9.8/10 (for a red laser, compared to other colors my rating would be 7.0)
Dot Divergence: 5/10 (acceptable, with other lens like G2 would be very uncomfortable)
My Final Rating: 9.5/10

Battery Required and Direction:
Required 2x18650 or 2x18350
Direction: Positive '+' to body and the Negative '-' to switch.
both with head top, if they are flat use an adapter like this https://es.aliexpress.com/item/100500...

Diode: I don't know, if anyone has an idea leave a comment
Working Time: unlimited, (but recommended not use more than 80 seconds)

3:17 power tests (911mW peak, 1149mW direct from diode without lens)
6:26 daytime test and comparison with 638nm 500mW
8:15 darktime test

13:57 safety glasses
14:29 comparisons with other lasers: 500mW 638nm
16:29 with model 890 80mW 532nm (RIP dpps cristal lens today 15 june, now actually is a 808nm 200mW Infrared, I think it will be my last dpss 532nm green laser because is a system that I really don't like, all their models are from cheap factory and effectiveness is poor, single diodes are better and more secure, I'm looking for a 520nm 100mW one for replacement)
17:15 with 1.6W 450nm blue
17:53 with 1.3W 525nm beast,
18:32 with 200mW 650nm red

and thx for watching, to complete the legion of the five 1W lasers I would be missing 405nm purple and 465nm bright blue, I will most likely get the blue one first because is much brighter.
support with like sub comment, If there is a problem or error let me know, thx2
