Dragon Lasers red laser pointers feature high power and very competitive prices. 

Advantages of the New 637nm Laser Pointers:
 
1. Most red lasers pointers are at wavelengths near 650nm. The 637nm lasers are brighter than 650nm lasers of same power.
2. Red lasers at wavelengths from 600nm to 660nm are all diode lasers. Diode lasers normally have a rectangle beam shape/mode. The beam mode of our 637nm lasers is perfectly collimated and the beam shape is near round. 
3. Our 637nm laser pointers have excellent power and very long duty cycle compared to other red laser pointers.

GERMAN:
Vor 2 Tagen erhielt ich den Laserpointer Viper 637nm mit 50 mw Ausgangsleistung. Da ich in Deutschland wohne, habe ich den Pointer zu einem Verwandten in Frankreich schicken lassen, und von dort dann zu mir. Dies hat gute 2 Wochen gedauert. Nun zum Pointer:
Die Leistung des Gerätes enspricht den Vorstellungen die ich von 50mw rot hatte. Die etwas hellere Färbung im vergleich zu 650nm ist gut zu erkennen (Das Rot hat einen deutlichen orange-Stich.) Am Tage kann man den Punkt auf einer weissen Wand noch deutlich in 300m Entfernung sehen. Durch die sagenhaft niedrige Divergenz ist die Lichtkonzentration auch in weiter Entfernung noch auf einen sehr kleinen Bereich gebündelt. Die Sichtbarkeit des Strahles im Dunkeln ist vor dem Pointer gut, hinter dem Pointer in Ordnung und von der Seite eher dürftig je nach Wetterlage. Für Starpointing reicht er aber aus. Im Nebel ist das Gerät allerdings ein Traum wie ich gestern festellen durfte - die niedrige Divergenz macht sich gerade hier auch in beträchtlicher Entfernung vor dem Pointer positiv bemerkbar. Für kokelfreudige ist hier allerdings eine Lupe Pflicht und selbst dann nur sehr eingeschränkt (dunkles Plastik). Die Verarbeitung macht einen guten Eindruck, wie man es ja vom Viper gewöhnt ist. Der Powerknopf ist schwer zu drücken, was die Gefahr einer unabsichtlichen Aktivierung des Gerätes deutlich mindert. Da sich die Temperatur des Pointers auch nach den angegebenen 3 Minuten nicht spürbar erhöht, wäre ein wenig mehr Ausgangsleistung meiner Meinung nach kein wirkliches technisches Problem. Alles in allem bekommt man für die 58 € + Versand aber einen sehr guten Pointer der nur die Höchstwertung bekommen kann.

ENGLISH:
2 days ago I received the laser pointer 637nm Viper with 50 mw output power. Because I live in Germany, I let the pointer send to a related in France, and from there to me. This took a good 2 weeks. Now for the pointer:
The performance of the device corresponds to the ideas I had of 50mw red. The slightly lighter color to 650nm compared can be clearly seen (The red has a distinct orange stitch.) During the day you can clearly see the point on a white wall still 300 meters away. By fabulously low divergence light concentration is still bundled in the distance on a very small area. The visibility of the beam in the dark is good before the pointer after the pointer in order and from the side rather poor weather permitting. But enough visibility for Starpointing. In the mist the device is a dream as I could determine yesterday - the low divergence makes particularly here at a considerable distance in front of the pointer positive impact. For friends of burning here is a magnifying glass obligation and even then only to a very limited (dark plastic). The processing makes a good impression on how it's used by the Viper. The power button is hard to press, which significantly reduces the risk of inadvertent activation of the device. Since not appreciably improve the temperature of the pointer after the specified 3 minutes a little more output power would, in my opinion, no be a real technical problem. All in all you get for 58 € + shipping but a very good pointer. It can only get the highest score.

I ordered the Spartan 90mw and it arrived in about 10 days in good package. This laser is as bright as my 220mw 650nm, and I can see the dot very well even at 2000 meters , the beam at night is well visible .This is a very good quality laser, and a serious company.

This red laser 90 mw suited all my needs. I have to align optical eyes that are over 100 feet from each other- no problem seeing my mark with this laser. Very reliable, excellent construction.

Bought a red laser pointer from Dragon and the service, delivery and product was everything I expected. No problems and a great product. Still going strong a year later. Hint buy extra rechargeable batteries and charger. They do last a long time though. I would recommend this company.

Viper 640nm 80mW

As with your other lasers, the Viper Red is quite impressive. A lot of power and a very tight beam in a very compact package. It seems to be very efficient and makes very little heat in spite of 80+Mw in such a small package, and an incredibly tight beam also.

The beam on this one is a perfect circle and only a slight variation in brightness across the beam. (No odd Pacman shapes like the red Spartan.) This one is going to be a graduation present. I am sure my nephew will be very pleased.
