Cheap 18650 zooms for scopes — state of the art?

Hi, it’s been a few years since I bought my Sunray King. I’m still very happy with it, but I get most use out of a cheapy 18650 Ultrafire. I decided to buy a cheap zoomer for attachment to a scope. This is what I chose. It cost £12 with shipping.

I was quite surprised at what the zoomed beam pattern looked like. Clearly won’t work with a scope. Is this the best bang for my buck or would I see a significant upgrade for £20-£25? Presumably with a single LED. I’ve not tried this thing zoomed at night but the flood setting seemed okay, so my money wasn’t entirely wasted. Thanks!

What’s wrong with the led beam? It looks bad at a few inches from the wall. I bet at night it will just give illumination. Like every other light. Unless I’m not understanding? My wife says I do that a lot

Thanks. Haha. I know the feeling.

At 15 metres, standing in the garden and shining down the hallway, it’s illuminating the entire front door with a pattern of 12 bright but widely spaced squares of light. The diameter of the spread looks to be over 2.5 metres. LOL!

Can anyone recommend a good single spot zooming 18650 flashlight for around £10-15 that will work with a scope? I need a tight beam. Thanks!

Oh… wow. Ya you get that with a large die led. Sorry I can’t be of much help. I don’t use zoomies

I don’t, usually. Thanks for the input, though. I guess some advice on the best single led emitter for a zoomer would be good if anyone is listening?

By the way, that pattern is not the flashlight a few inches from the wall. It’s 6 feet from the ceiling!

An XL-l is a pretty good emitter for a tight beam. So is an XPG3. And an SST 20. I believe Osram makes some. As well as a Samsung. But I have not tried those. I am a very big fan of the SST 20. But have not tried it a zoomie

Thank you. That’s helpful to know. The names and bins of the LEDs have all changed since I was an enthusiast. I don’t know what’s what any more.

Me too. I'm an incan guy for the most part. I do t have any of these large die LEDs. But I do know the smaller the die, the more throw you get. Which is my preference. I do not like floody lights. I want what I'm pointed at to be lit up and nothing else so I can preserve my night vision. Plus I don't need to see what I'm not looking at!
The sst-20 in 4k or 5k is my favorite led. It throws quite well even in a small reflector. So it should work in a zoomie quite nicely. But you can still push it to close to a thousand lumens if you wish.
