For example, Lum-Tec is recognized in the luminescence arena for their process of applying 6-8 layers of Super-LumiNova over a pure white base to produce a long-lasting, dense glow. This is why some watch brands advertise that they apply multiple level of lume to their watches. While this newer formula of Super-LumiNova is said to provide a brighter and longer lasting glow, traditionally the more lume material you apply to the dial the brighter it will be. For example, C3 (green) is available up to Grade X1, but the BGW9 (white) is only available in Standard Grade or Grade A. Note: It appears that not all colors/pigments are available in all grades. It does not mention what the performance increase is when comparing Grade A to Grade X1. This increase is based on a comparison between Standard Grade and X1 grade. According to RC Tritec, Grade X1 lume shows improvements of up to 60% after two hours. While tritium will give off a glow whether you charge it up or not, i can say without any uncertainty that luminova when properly charged will easily last all night.Grade X1 is the newest formulation of SLN. In AliExpress, you can also find other good deals on mechanical wristwatches, watches accessories and. i can attest that the lume on my sub gave off a steady low green glow for the entire night, from the moment the last lick of light from the sun set to the moment the skies started to brighten again. Lume watches, a sport watch that looks the same time. it was a supremely boring detail but, there i was doing it. On one of the exercises i was on maybe a year or two ago, i remember that i had to man a trench overnight. Luminova may SEEM to be a relatively short lasting lume, but trust me when i say that it glows for a long, long time. even when you're out camping, or roughing it in the field with your comrades, it's near impossible not to have some random light source mess with your night vision. In the cities, there is so much light everywhere that it is very easy for our eyes to lose their night vision. you can't turn yourself more than one degree in any direction from stationary without seeing a source of light. everything is electronic, and everything is powered by electricity. I think the thing that people need to realise is that we live in a hyper electrical world. That's the only application where I can imagine where the Tritium was actually superior to the current Chromalight. I would assume you have had the rare privilege of using one of the 5517 Mil subs with the sword hands back in the day. To all those who long for the "good old days of Tritium". I would rather have the modern lume any day over Tritium as I know my Chromalight will be going strong well and truely after the Tritium has died. Given the superior life span of any of the modern lume variants as opposed to the limited life span of Tritium. I would imagine that any diver planning to dive at night would have a source of artificial light to see what they were doing and where they were going, so luminosity wouldn't be an issue anyway.įurther to this, Super luminova is slightly better again than Luminova and Chromalight is slightly better again than Super Luminova. I consider this alone to be more than adequate and fit for purpose for the vast majority of end users. After that it starts to fall away below Tritium in performance. In real terms, initially even Luminova is superior to Tritium for about 30 - 45 minutes after a charge. Our reliable, functional, dependable and sturdy timepieces can withstand. I have seen charts in the past that map out the relative performance of the different types of lume. ALPHA MARINE AUTOMATIC BLACK CERAMIC BEZEL FULL LUME CHERRY RED DIAL BRACELET. That's why my DSSD is the go to watch for daily wear. Chromalight rules as far as I'm concerned and is perfectly functional. The brightness of the lume immediately after going from outdoors in the sunlight to a darker place in the shed makes it more than user friendly, and is superior to any Tritium I've had in the last 40 odd years. It's superior to my Seiko diver and any Omega that I currently have/had. They offer a distinct look that provides the ability to read time at any point in the day. Now, lume watches are loved by watch enthusiasts and for good reason. The lume lasts all night so I can read the time in the dark if I bother to charge it a little before going to bed. Lume watches were initially designed during the first world war because of the need for soldiers to know what time it is in the darker hours. No problems with the chromalight on my DSSD.
