Why the need for such a wide reflector? Wouldn't it work nice to have a loooong deeeep narrow one?
Imagine a flashlight made primordially of a couple stacked together tubes: one for the batteries, let's say 4 26650s in series, and the other for the lens/reflector/emitter/driver, so 9+" deep reflector without issues. :-)
LoL!
How about a full spectrum laser? I swear I've heard something like this somewhere… maybe in another forum. ;)
Oh yeah, I agree. I had negotiated them down to a great price way back when, but they would not budge on quantity. To give you an idea of its performance, here is a quote from what they told me about it:
"Yes, we have a special Luminus CST90 reflector which achieves >100cd/lm and is an ultra-specular reflector with no facets for military spot light applications."
I’m definitely interested. Hi CRI thrower sounds awesome. I’d be nice to beat 1 million candella. Reminds me of a spotlight I used to carry in the car that plugged into the cigarette lighter.
For other comments - the intent of the project is max throw, so depth in almost insignificant compared to width. Depth limits the width of spill. It should be a thrower LED - XHP35 HI, XPL HI, possible XP-G2 but don't think that would be an option unless we can do a true factory dedome, or if an XP-G3 HI comes available. Going with an XHP-70 on SMO would have the hole, less throw, but can be considered. To me, the best stock emitter choice would be the XHP35 HI, but would love to see 1 mcd broken with a dedomed XP-G2, or possibly dedomed XPL W2/W3. A couple of manufacturers are doing or did factory dedoming, but the XHP35 HI and XPL HI are kind of killing that direction.
I would get several of those no matter what they are yet i would like to see the host form of it, it seems that XHP35 will prevail at the end so at least let us the host option and W3/XLP2 ftw
Whats the idea behind the high CRI option in a thrower?
If you’re really trying to make a large diameter light, I recommend designing the large diameter parts in segments that are an inch or two thick. Go much thicker than that and prices for stock go through the roof, and that’s if you can even find what you want. For example, to fit a 120mm reflector, you may be looking at a 6 inch cube, so you’re starting costs off at $118 per light plus shipping if you buy that from McMaster. Take it down to smaller segments like I suggest, and you might be able to find suitable hunks of aluminum that local shops are scrapping, which in my city would cost roughly $10 per light for enough stock to build an assembly that large.
I’m in, lantern style (top handle) would be my choice, with a reflector this size a pluger type will be unpleasantly unwieldy, while you great minds are at it, why not make it vailable in a number of LED choice XHP35, XHP50, XHP70, anything under XHP35 die size with a reflector this big will throw a somewhat useless laser like beam.
Would like a very strongly driven neutral XHP70 personaly, it should give a relatively broad beam with around 200Kcd throw, a more practical K60 on steroids.
I love Djozz’s design btw, looks like the center of gravity could be aligned with the middle of the handle, perfect balance.
