Unless there is a radical shift in consumer preferences, it's just not going to happen. I've been on CPF a decent amount of time and love spending time on here, but listening to CPF is a good way to severely limit sales for production manufacturers. Enthusiasts are not aligned with the mass market in pretty much any industry. We want better, faster, stronger, higher performance, etc. and all that costs more and requires more knowledge/preference than the average consumer wants or will ever have. Even spending $50 on a flashlight is crazy to a lot of people.
So, let's go down the list of some of the ones I see a lot:
High CRI? The average consumer overwhelmingly prefers cool white. You might think it's salesman bias, lumens, whatever, but we show people the beams side by side all the time without telling them anything about lumens, tint and what it means, or anything else and they usually want the cool white. Even when we explain the benefits of the higher CRI, they want the cool white. I personally prefer neutral and High CRI, but it would be foolish to discount what the majority of the market wants. There is definitely a large part of that cool white group that just wants max lumens and doesn't care about tint at all, but we see over and over that people just like cool white tint better.
Strobe? That's the #2 thing people ask us for after max lumens, but you would think it gives you mega-cancer if you read CPF.
Beacon/SOS? I have yet to talk to a customer that has used SOS in a real-life situation, but people want it. I know a lot of people that use beacon on a regular basis, mostly for letting people know where they are with increased visibility.
Aggressive Strike Bezels? People love them and we sell them all day long.
Green tint? The Olight M2X has a pretty darn green tint, but it has a beam distance of 800m and that's all people care about. They usually comment on how it is green as they walk up to the register to buy it and then again when they come to buy a second one for a friend. Granted, we do have a lot of enthusiast customers who do not like green, but they are the exception, like everything else above. Heck, a lot of hunters look specifically for green tint because they say some animals that cannot see the color (not sure of the truth on that).
As others have mentioned, neutral and High CRI inventory just sits on the shelf. Several people have pointed out FOURSEVENS and I can tell you that they are not an isolated case. We see far lower sales with anything other than cool white across the board. The one exception is headlamps. Cool white headlamps still sell better, but not with quite as dramatic of a difference. Spark is the only brand I can think of where the sales are even close, but they admittedly do a great job of choosing tints for their neutral models.
My point is that a lot of people like and use things that we don't like and that's not a bad thing. There will always be the niche guys that make the tints, interfaces, features, etc. that we want and there will always be the mass market guys that make what everyone else wants.
