Most people who use flashlights don’t care about these things. We are the aberration in the marketplace. When it comes to work lights, none of the stuff we care about matters. When it comes to portable industrial/utility lighting, all the stuff you care about is here, it’s just not sold at the hardware store.
Keep in mind, the original work light is a socket with a metal spring and a stamped aluminum reflector. They are still around. They cost all of $7.
The main requirement for work lights is that the thing that was dark is not dark anymore. After that you care that you have enough light. Then after that you care if you can plug it in. Color reproduction doesn’t matter for framing and wiring. Halogen work lamps made headway into the market despite costing MUCH more because they brought more light in less space and since you had to keep them from setting things on fire, they brought new useful mounting solutions with them. The physical packaging for protection also means you didn’t have to worry about bulbs getting burnt out as much with the cheap designs either. Carrying two $80 dual head halogen set ups saved space and effort over carrying 8+ $7 specials.
You don’t care about PWM dimming because you aren’t going to dim the thing. No one lamp is ever going to bring too much illumination to the job. You will either be cursing wishing you had more lamps, or you will simply not use all you have. The plug or power switch is literally your dimming control.
The battery operated bit that LEDs have brought to the game is the reason LEDs are getting adopted on merit. (LEDs are showing up also just because of governmental regulations). Some people have need of this. Homeowners and mechanics will love it. Contractors and such less so. If they have no juice they have generators on site for other reasons. But even then, much like cordless drills and such, they probably will have a couple on hand for expediency on small jobs.
In very few instances will someone care about work lights and color reproduction. The original work light is a socket with a metal spring and a stamped aluminum reflector. They are still around. They cost all of $7. If you have color reproduction needs, you can go a a couple of aisles over and get specific color temp high CRI bulbs for $3 a pop. $10.
If you are REALLY serious about needing portable color controlled lighting you go to the existing market and just buy LED lamps for video work.
If you needed battery operated scene lighting, you used to go to the specialist industry manufacturers for them. But LEDs and high density battery offerings are just getting too cheap and commoditized to support the premium niche industry. Which is why you see mass market brands like milwaulkee getting in on it.
I love my flashlights. I’ve spent tons on them.
I’ve got a ryobi battery powered work light. It is incredibly useful. You can’t make me care about it’s color reproduction as it’s just not relevant to how they get used. I might buy another one or two and more battery packs.
You can’t compete on features the market doesn’t care about.
