I can't say because I can't see what you're talking about.
I hit on the link and it's under maintenance. I can say this about LED lights, most of them are great.
Last year I picked up a small 6 in long Strion, rechargeable,flashlight made by Streamlight. It is amazing,just awesome !! The amount of light it puts out and the distance, plus the amount of use time because of the small drain LEDs put on the battery makes it my favorite flashlight. And I thought I had a great flashlight before which was another by Streamlight but it has a halogen bulb.
I have been watching the LED light progression and they have come a long way and we are going to see more of them, but it does not mean all LEDs are great.
AS with anything today, their are manufacturers who push a product using the hype created in a name, like LED, but don't put something out there worth a squat.
I was able to try out the flashlights I got before I bought them, and after seeing how they performed, I wanted one.

That's the problem with a lot of stuff today, it's in some package you can't open, you can't see how it works, just believe the claims on the product....like HD, Industrial Grade, Commercial Quality, New and Improved, etc.
If it was me I would want to try it out first, or know I can return it, bu then I really get tired of returning stuff that doesn't work. It's time consuming.
I hope all this babble helps with what you were asking about.
