Who sells high power lights that focus?

While I am waiting for my first high power light to come (TR J18) I noticed when I was looking I didnt see any lights (>2500 lumens) that you could focus from spot to flood. Did I miss them? Who makes them and what is the cost? Thanks.

The J18 gets its tremendous output from 7 leds. Nobody really makes focusing optics for 7 separate leds.

Yeah, thanks. Looking some more in this forum it seems like around 1500 lumens is the biggest focusing light you can get.

Those aren’t 1500 lumens if it’s only 1 xml.

Specs probably over rated then. I am finding out that most companies aggregate the lumens of their lights. I guess 1000 lumen light with focus can make it appear as bright as a much larger light which only has flood.

So my next mission is to find a nice pocket size light around 1000 lumen with focus and belt clip. That would be nice….

The focus lens does the same thing more or less as an equivalent size reflector. xml’s are typically 500l or so. However, given the large size of the head on that J18 you bought * 7 leds compensates for larger spot with sheer power.

There ain't any 1000 lumen with focus... if you're lucky you find one with 600-700 lumens.

Might want to search for XM-L Flood to Throw and check out some reviews.  Some of them burn up rather quick (i.e. SK98).

>>>>>Some of them burn up rather quick (i.e. SK98).

The “real” sk98 sipik gets mighty warm mighty fast, but mine has yet to burn up. I read one BLF review where someone left a sipik 98 on and it toasted, but I think probably a high percentage of overpowered lights will also burn up if left on unattended in turbo for long periods of time.

The ultrafire sk98 ++clones++ work fine, better than fine, like my EDC for the past 4-5 months. In fact, they work GREAT. The flood is brighter than the flood setting on the UniqueFire UF-T20. Although the zoom on the T20 is much brighter than the ultrafire sk98.

I bought mine from here, although there is no promise that the new clones are the same as the one I have. Someone on BLF said that the pills were no longer solid aluminum, but still worked fine.

You also might want to try the keygos m12. Love mine. a REALLY usable zoom light.

http://www.keygos.com/product_info.php?products_id=954

Sometimes they use a metal o-ring as the zoom tensioner, but changing it to a “real” o-ring takes a trip to Home Depot and about 5 minutes.

Hope this helps!

Led Lenser X21R but it’s pricey.

Although watch those Chinese lumen claims on other budget lights. As in reality I suspect there are actually few production lights over 2500 lumens. Let alone zooming ones.

You are going to have a tough time finding any single XML that puts out more the 800 lumens. And for flood-to-throw lights, you lose half the light output in throw mode.

Almost all zoomable lights are effectively projectors. In throw mode, they project an image of the LED surface. With multi-emtter lights, you would get a separate image of each LED, not all of them focused into a single spot.

They’ll more or less average out at a reasonable distance similarly to multi-emitter reflectors. A reflectored hotspot image is after all an integrated die image over the surface.

Nope, you’ll get an array of spots (this assumes the flood-to-throw is using an aspheric lens). I put an aspheric lens on a Bridgelux array (with LEDs spaced MUCH closer than something like an 6xXML light) and you get an image of lots of dots. A multi-XML would be an image of fewer, but bigger spots.

I thought you were discussing Chicken Drumstick’s post/image right above yours, not one huge ass optic over everything. We’re talking about different things. Smile

Was going to say LED lenser x21 but it’s already been pointed out Oops

I’ve been thinking about this and wondering about the possibility of a reflector that changes shape rather than moving the led in/out. Sort of an iris effect. To me, the ideal zoomie would go from spot to flood by growing the spot smoothly rather than merely going out of focus. Maybe something like a polarizing filter would be easier. Turn the bezel to increase/decrease diffusion.

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

A typical flashlight parabolic reflector produces “out of focus” (or at least non-image focus) view of the die. Zoom to throw aspherics for the most part seem pretty smooth to me.

Hi guys. Got my UniqueFire UF-T20 yesterday, my first focusing light and my third LED light. It seems to work good. The flood setting is nice and big with no hot spot in the middle. The throw setting is strange, I see an image of the LED, square but bright. Very interesting. I did a quick check last night comparing it against my CREE LED XM-L T6 1200LM which I bought from Tmart last week. The T20 on throw was brighter. On flood the T20 was slightly smaller circle and dimmer. Of course both were swamped by my J18!!!

Hey Joe:

A belated welcome to BLF!

>>>>> I see an image of the LED, square but bright.

Yeah, that’s always a shock for most the first time they see the emitter blown up like that. I thought mine was broken when I got my first zooomer. I rushed to meritline to complain but quickly found that it was supposed to be that way. heh heh oops.

The T20 is a nifty zoomer. I wish I didn’t have to twist it to zoom, but I’ll live. Wink The best zoomer of all time is the small sun zy-c10-s. That thing throws forever.

I also really like the keygos M12 …. My cat got out the other night and he’s a 1000 years old and gets lost on his own outside, so I grabbed the closest light (which happened to be the m12) and went to look for him.

At first I was kinda bummed because I thought a fixed focus would work better in the great senile cat hunt, but boy was I pleasantly surprised. I could use the zoomed out spot to look under cars at a much farther disatnce than I ever could have with a fixed, because the spill in the fixed would burn out the car so I couldn’t actually see under it — if that makes sense. As a result, I have been impressed all over again by the m12. Strangely, it seems brighter than the keygos m10. (I’m expecting some emitters and drivers and will replace the driver and emitter in the m10; it’s great light. Just needs to be brighter.)

And, yes, I did find old edgar the cat — like a 1/2 mile from home — heading for the park to set up a homeless cat camp or something. Then I had to carry him back the 1/2 mile squirming and trying to bite me. He has really bad arthritis in his rear haunches, so he doesn’t like to be picked up. Oh the things we go through for our stupid pets. Wink Certainly wasn’t a big game hunt or rescuing someone froma burning building, but the m12 sure came in handy and worked great.

Other zoomers of note are the sipik sk98 clones (made by ultrafire) and a TINY sipik sk73. It burned up about a month ago, and I finally got around to putting in a u2 and a nice driver. Now the thing kicks butt. Like it so much that it has taken the place of my 2011 for a bit as an EDC. The sk98 clone also has been an edc for me at times. Certainly not in the league of a brightness king like a ke-5, the sk98 clone is still plenty bright and comes in handy for me because of its versatility..

Ubehebe, good story. We have 5 cats, all black, all indoor cats. They have escaped once or twice but thank God during the day.

So far I notice the T20 gets alot warmer than the other lights. Not too warm, however. What is cool is I am uisng batteries I salvaged from a Lenovo laptop. Got six really good, 4.1 v Sanyos out of it which power this new light nice.

Not so with Led Lenser flood to throw lights. They’re overpriced, use outdated emitters, are often poorly driven and typically have ringy beams, but they shine when it comes to output in throw mode. The T7 is a valued member of my collection.
