just like a conventional reflector the bigger the led the bigger the hotspot. I have a stock E10 and a E10vn with W2.1 that does double the lumen. The E10vn has a hotspot twice the size double the lumen but the same intensity
Thank you, but that still doesn't explain Vinh's measurement numbers when comparing the two lights and LEDs...
- Spec 1 E10vn W1 6500K @2s = 560L, 160Kcd, 800m
- Spec 2 E10vn W2 5400K @2s= 730L, 120Kcd, 692m
Notice the specs from the Skylumen website above, the different LED W1 vs W2 results in different amounts of intensity and throw.
But if you compare the Manker MC13 specs:
- Spec 1 Stock MC13 W1.1 6500K @2s: 600L, 160Kcd, 800m
- Spec 3 MC13vn VNX2 W2.1 5400K @2s: 1100L, 160kcd, 800m
Different LED here produces the same throw / intensity, unlike the E10 mentioned previously.
It would stand to reason that by switching from W1 to W2 (without Vinh's boost) in the MC13, that there would be a similar loss of intensity and throw, and add ~200-300 lumens. However due to Vinh's boosting the driver... he gets more than 200-300 lumens, nearly double, and therefore the throw and intensity of the W2 does in fact increase to equal the W1.
I believe it is by coincidence that there is no change in throw/intensity, due to the boost, but without the boost, the LED swap would = less intensity / throw.
You are comparing stock E10 W1 to Boosted E10vn W2.1. We need to compare boosted vs boosted, or stock vs stock. Otherwise the equal intensity/throw is possibly due to the boost on the less throwy W2 pushing it into the W1 intensity / throw equivalent.
Vinh, can you shed some light on this please? Would a MC13vn W1.1 with VNX2 driver boost push 200kcd and 850m throw?
