Solarforce "close-up" convex lens

I don’t know if this has been covered here but I saw this on the Solarforce sales site.

Solarforce blurb from website-

I’ve ordered one to see how “close-up” they are.

What this lens does is create the 'zoomed out' beam of zoomies, which can indeed be nice if you want an even illumination close by.

A fixed zoomed out aspheric? For myself, I can't see needing that enough to convert a flashlight. Just use a zoomie when needed, most cost less than this lens.

Edit: This sits deeper in the head, so it won't be as wide as most zoomies anyway.

Very interesting . I happen to think this beam profile is great for trail walking , as there are no artifacts or glare that can hide trip hazards .

I’m interested to see what it will do with a UV drop-in that I’m running with 6x3v primaries, if no good result I think it can go on my “wander around the house in the dark flashlight”.
At the price it’s worth having in the odds and ends box. If it’s any good I’ll be getting more, P60’s aren’t exactly known good as throwers anyway so flood it is.

Ok - I'm getting the ahorton thrower aspheric (From Calvin @IS) in the group buy, and gotta get 1 or 2 of these. I would assume these will work like a TIR optic in a EDC - wide angle. I got these: fasttech-45-degree-angle-optical-lens-5-pack, and the beam profile is same as a zoomie in spill mode, so I assume this SoalrForce will have the same effect - I find them useful.

My L2M hangs surprisingly well with the throwers with a de-domed XP-E2 R4 1C/Q-lite/4x7135's/SMO.

I’ve not got much to compare to, I have a stack of L2 bits, enough for 8-9 lights if I put them all together but as they’re all P60’s There’s only my Nitecore MT2A to compare them to, all of them are good at dispelling the darkness enough to see where I’m going, which is what I bought them for so I’m happy. :slight_smile:

The lens arrived today 13 days via Hong Kong Post put it in my “house exploring in the dark” light and it does what it says on the tin, absolutely no hotspot all flood. It makes the drop-in look underpowered but I expect that will be because the light is spread out rather than in a tighter cone.
Pretty much what I expected and wanted.

What happens to the beampattern, if you put another aspheric on top of it (swap the glass lens)?

That’ll depend 100% on the focal length of the lens you put in front, it could make it zoomed in (albeit with quite a bit more lumen loss than zooming in a single lens zoomie) or not do much at all (again other than cost more lumens). Most likely with any cheap lens you get the focal length will be much farther of a distance than the few mm in front of this lens the second one would be held. You could check edmunds for a 26mm lens with a shorter focal length but the cheapest
lens they sell is $30 for a single one and again one final time you’re going to be paying more than the light is worth for a lens that’s while might be a cool concept is really gonna cost you a lot of overall output.

would I be correct in thinking that this convex lens mod/swap would be great for using in a bicycle headlight setup? I’m assuming the round beam would make it much less annoying to cars on the road (versus a standard OP reflector that has a lot more flood).

Thoughts?

I don’t think so Tucker. There is no throw at all when in the bezel. It makes the light output look like a mule type of light. Very floody with zero throw. Used for up close work.
It does throw a big, concentrated, circle of light though. :wink:

thanks bud! your explanation was perfect! I’ll stick to an OP reflector for my bike then

A long time ago I converted a P60 to do this with a DX aspheric lens in the host.

One of my favorite lights for walking at nights and hobby work.

I tried this convex lens yesterday. It will screw perfectly on a intl-outdoor CUXP2 or CUXM2 P60 drop-in. It is very nice and doesn’t alter the LED tint at all, useful for walking and in-house use (coupled with a firefly mode this would make the ultimate piss light :slight_smile:

It’s been on my bedside table since I bought it connected to an L2N with a weak but good enough 280-300 lumen drop-in with 1 mode, I’d like the International Outdoor CUXP2 with 4 modes including firefly but what I’ve got is all I need.

I have one of these in my Solarforce L2C along with an IOS CUXM2 T6 4D drop-in with 4-modes. Fantastic little light for walking around the house.

I've had one for a few days in my L2M. I like it paired with an intlOutdoor drop in all modes are good, moonlight to max.

At that price it's worth checking out.

These work ok for mild bicycle use, for city street riding — they don’t throw, but they do fill in shadows as you get close to them, in time to know if it’s a crack or stick or bump.

The big round circle still throws a good bit of light into oncoming driver/rider’s eyes, adding some kind of “visor” might be helpful.

So far every P60 I’ve tried — none de-domed — the emitter actually touches the lens on these things — is that what others find?
