They are two versions of the Helios 4.5. One is focusable the other is not. It is another $150 or so for the focusable version.

I usually leave it in a tight beam also but when I'm assisting my buddy on a placement or wrap, I sometimes spread the beam out to better fascilitate the job. For signals, hands down, tight spot is where it is at.Well i am under the impression it is focusable underwater. The halcyon instructions dont warn against it although i dont think i ever focused it under water leaving just it on the tightest beam setting. You may want to email halcyon to be absolutely sure.

Yes and no. The 10 watt lighthead is extremely small and compact compared to the 18w light head. The 4.5 cannister is also nice and compact and light weight on dry ground. The 10w produces a nice pencil like beam where the 18w produces a larger more powerful spot. If i had to do it all over again i would stay with my 18 as it really cuts through the crud in murky waters and produces a nice big spot during daylight diving for looking in crevices, looking under rocks and such. Either way i seriously doubt you will be disappointed with the 4.5 if you go that route.
BlueDolphin:If you had a choice between the Halcyon Pro 6 10W, or the Helios 4.5 10W, which would you prefer and why?
Thanks
