NEW FEATURE: Alpha Primary Seal Ring (PSR)

As you know by now, I can't leave well enough alone. I pressure tested my lights to 300 feet for 5 hours...but that's just not good enough is it? What can make the Alpha even more bullet proof (water bullets)? Enter the Alpha Primary Seal Ring (PSR). It doesn't increase the depth rating, but it should extend the exposure time and improve the sealing performance under extreme physical conditions, like impact, vibration, temperature, altitude, and submersion.

Actually, it would be cool to carry an Alpha up to the snowy summit of a mountain and then down to the ocean and into a 300ft scuba dive. Anyone want to meet me in New Zealand?

The PSR makes the front seal 110% effective (that's a guesstimate)

As far as I know, this is also a completely novel method for sealing a flashlight. Patent worthy even, but now I've done it, since I posted this picture it can't be patented...by anyone...and I think that's fair :) I digress.

This ring is custom made from 302 stainless steel, just for me, by Smalley Steel Ring Co. out of Lake Zurich, Illinois. It is now a standard feature on all Alpha lights. It does make it a little harder to remove the o-ring and get to the lens, but you should really never need to do this unless the glass get broken or severely scratched over time.

Just in case you feel the urge, you'll need four things: o-ring pick, bent nose pliers, a replacement o-ring, and the link to this video. The pick and pliers are included with the Journeyman Package. They can also be purchased separately.

I do want to note, this seal is not absolutely necessary. I tested my light to 300 feet for 5 hours without the PSR in place. Unless your light is routinely in wet environments, I wouldn't worry about it. However, I want to send out a light that is as close to 100% reliable as possible, and this checks off one of the boxes that has been bothering me.

The PSR will be available as an optional upgrade for all existing Alphas, but not until the new year when things quiet down a bit. Please don't email me until then or I will just forget :) Alpha-Blue label owners, this is a free upgrade!
