Here comes A1, a thrower sized between C8 and Emisar D1.
The host has the same basic architecture as A3. And the same major features.
It’s just 1 LED and a reflector instead of 3 LEDs and a TIR.
Reflector has exactly the same dimensions as Phoenix Electroforms PA19.01, so for the big budget users there’s an easy upgrade path.
This part costs $45 when buying 1 piece or $35 when buying 100. So manufacturer could offer it together with UCL2 window as a $50 option. Expensive…but I’m sure there would be buyers willing to pay so much for ~15% higher performance.
I got troubles picking LED for it, there are quite a few good options.
1. Dedomed LH351D:
- Cheap, especially considering that it’s a part of A3 / A7 lineup already
- High CRI throwers is untapped niche. LH351D enables the use of this LED
- Available in warm white
- untested throw
- probably OK, but worse than any other mentioned here
2. XHP35 HI
- very high efficiency at medium-high currents
- possible high-cri
- possible warm white
- expensive
- requires expensive driver
- and actually a different driver, adding R&D costs
- at peak power it’s going to oveheat quickly
3. Dedomed SST-40
- quite cheap
- good throw
- quite efficient
- only cool white
4. Osram Q8WP
- moderately priced
- extreme throw
- low efficiency
- only cool white
My choice would be to offer both Q8WP and LH351D. Q8WP is a really great thrower LED. LH351D covers the cases where it can’t do for minimal additional cost to the manufacturer.
Doing some performance analysis…let’s drive Q8WP to 7.3A to get round 1500 LED lm (note: this is Turbo mode, the light won’t sustain it). According to Enderman’s calculator with the upgraded reflector and UCL2-class lens this light gets 190 kcd and 1410 OTF lm. OK, minimal amount of dust and regular manufacturing tolerances will reduce it. Is 150 kcd and 1300 lm conservative enough?
With cheap alu reflector and regular AR coated glass calculations show 170 kcd and 1290 lm. Because of machining defects, the difference between calculations and reality is likely to be bigger for this one.
Dedomed LH351D should offer very roughly the same lm and half cd.
