Neal’s superb thrower for the money C8+ Osram Flat white with prices ranging from $19 to $24…depending on choice of Aluminum or Copper MCPCB is not bad at all.
Neal’s C8+ hosts are sourced from Wainlight. Some other parts are sourced from his contacts in the industry.
Take a close look at the pics, from the host to the internal parts, the reflector, the tailcap/spring assembly…not you would expect from a complete small thrower Osram light at just about $20!
I got one of the white flat c8s ($15USD one) but ended up using it as a host for another white flat on copper MCPCB, and a 5A driver from Convoy, as the one that comes with it is 8*7135, so 2.8A. Thing is a monster; I’ll do throw measurements on it tonight. (Unrelated, I know, but good to see what’s possible)
5m is too close for a thrower like this. I do 10 or 15m otherwise you can get a higher reading.
The reading also depends on how accurate your light meter is.
At 4.7A (same 5 amp driver) I got 975m. I thought that was accurate until I saw 1lumen’s review on the FT03 SST40 at 950m while I got 1040m. I think my meter is reading too high. The review was using quite an expensive meter so I reckon their’s would be more accurate than mine.
Make sure you do the test outside otherwise the light reflecting off the walls will add to the result. Inside vs outside gives 20-30m difference.
Neal’s is only driven at 2.8A so it’s certainly not the claimed 1000m or the 700 lumens. Mine at 4.7A gets 720 so 2.8A certainly isn’t 700
Yeah, will have to do a test outside; pretty rainy here tonight.
That said, I reviewed the E10 (will be up on 1lumen soon) and got similar results at 5m inside to 10m outside, with outside giving slightly more distance. Zeroair got similar results to me, so I’m inclined to believe my lux meter.
Food for thought! Will replicate outside when the weather is nicer.
The CSLPM1.1G w/copper MCPCB model I bought is using a BLF A6 driver and is reading >4A on a 30Q using a regular mulitmeter with regular thin probe wires.
Looks like Neal’s C8+ Osram is the same as the Wainlight C8+ Osram NM1 in BG.
I measure 2.8 Amps max on the Wainlight C8+ Osram NM1, so probably somewhere like 500+ real lumens? (I have a lux meter but don’t have an integrating tube for measuring…)
I tried comparing visually a Convoy C8+ SST40 (“ramp” driver, which pushes around 7 Amps tailcap current on the SST40 LED), versus the C8+ Osram NM1 (2.8 Amps tailcap current) — the C8+ Osram appears to have a more intense (brighter) hotspot than the C8+ SST40 @ 7Amps. Although I find the C8+ Osram usability to depend on the situation, since it lights up a very small spot…
The driver on both my Neal C8 and the WF one in the OP clearly have A6 drivers though, not sure how that would be limited to 2.8A since it only has 1x7135 AFAIK.
Anybody have pics of the Wainlight driver? There may be different ones used for WF 1mm vs 2mm
