I bought the FIREFLIES E01 LUMINUS SST40W 5000K Version from Neal, at least I ordered exactly such one.
After unpacking and trying out I first noticed that the tint is more in the direction of 6000k (ramped to ceil) and in turbo mode it changes to like 7000K, clear visible blue cast in the beam. Then I noticed the clearly intense hotspot, some ugly artifacts and rings in the beam profile, I assume due to the bad centering of the LED. When I removed the bezel with the glass and the optic to view the centering of the LED, I noticed that the LED does not look like SST40 (compared to the FT03). I suppose it’s the osram led which is offered as an option for the E01, it would suit the light color and intensity of the hotspot. This built in LED is dome less, the yellow flatspot of the led is not square but rectangular and Osram is also written on the mcpcb (but that does not always have to mean something), at least I wanted to get a confirmation about my assumption.
Therefore i’ve done two pics:
I would be grateful for a few opinions.
In the end I would still want to have the SST40 5000K, then i assume it is a nice light with this LED the TIR-optic. But the tint and beam profile as it is right now with the Osram LED in combination withe TIR optic of E01 is horrible.
Someone, AlexGT maybe (could definitely be wrong there) has been looking into a reflector to fit since the E01 came out and has yet to source one.
I don’t have any interest so I’ve not looked myself, the TIR is well suited and performs so well I don’t see a need, but he’s posted several options he had tried and pics of failed attempts so I’m pretty confident in saying a COTS reflector isn’t available…
