Aspheric thrower...no spill 800meter plus...Incan or LED?

Other Types of Lights Non-LED Lanterns, Incandescent, and HID Lights

A mate was looking to get a long range thrower/ spotting type spot beam type lamp…as little spill as possible and a thin focuesed beam.

He had looked at a Wicked Laser 100W HID unit.

Also been considering an LED unit, an XSearcher –4s from Deerelight.

Is there any advntage over ican or LED for a logn range spot thrower like this.

Not really looking for suggestions of different lamps at this stage. nto worried about budget or price.

This post it realy just asking the question of the light source…is one better than the other for this application ?

LED + Aspherical lens is the answer.

Because most of the incan and HID lights on the market come with reflector, and with reflector you will have plenty of flood at the same time.

< thanks, yes that is what I went for a UF 1508 and also a Dereelight XSearcher
I was expecting the AS ;end to also have reflector.

I thought a well designed reflector would help the light to be focused and corrected to a parallel beam before it hits the lens

If money and flashlight size is not problem to you than nothing(literary nothing) cant beat this reflector light:

Yeah, that’s a whole other ballgame. An upside down reflector (wavien type collar) would actually focus all of the light back onto the led and then out of the lens. There’s threads upon threads of that here. You may luck up and find someone that can make you one.

Yes, J have come across those, and as you say a whole new ball
game. But I was thinkong more along the lines of the reflectors that are / were used in military style spot/search lights. They create a parallel
beam using a reflector.

Having a parabolic reflector behind an aspherical lens won’t help in throw at all - it’s pointless, but it will probably create more messy “rings” around your hotspot.

An ellipsoidal reflector however could focus (collect) your lightsource beam into a point and then disperse it into an aspherical lens, works well for incan or HID bulb as what we can see in many automotive projector headlamps, but again it is pointless for LED setup.

Note: An LED emits light in a certain direction, while light bulbs emit light to all directions (360 degree), hence it makes the difference.

High power led and reflector mounted recoil style would give a pencil thin beam without spill.

I was planning to do that, but I looked for any other peoples builds using recoil+LED and only found one build which was meh, so I have nothing to go off and little inspiration.

Maybe some time in the future if I have spare moneys I will try that.

It will be much larger than an aspheric flashlight but should have a tighter beam from my calculations.
