AD200 Evolv Twin-Head Adapter: Can it meter enough power for the brighter AD360 bulb as released?

Epic Battle of the Bulbs! Faster than a Cheetah on a Caffeine Jag, more powerful than a Godox on Glucagon, able to illuminate tall buildings from a single FlashPoint, it's the Evolv Twin Head like you've never seen it before! "In this socket, The heavyweight AD360, weighing in at a conservative 360 watt-seconds maximum power output." "And later, in the very same socket, the Bantam weight AD200, with its svelte form factor and trusty 200 watt-seconds power max." How did these two bulbs fare, mounted in our modified Evolv 200 Twin-Head adapter, "head-to-head"? And can the bigger bulb really deliver the brighter goods? Find out as we test, meter and expose all in this video! Equipment used: FlashPoint/Godox eVolv Twin Head Adapter , modified to accept and fire both AD200 and AD360 bulbs, as initially envisioned by the manufacturer Gossen DigiSky Professional Flash Meter PC Link to 3.5mm connector cable to sync the meter to the eVolv flash Trigger Stock AD360 and AD200 bare bulb xenon flash tubes Control rig to stabilize and precisely place the meter and flash at consistent test distance iPhone to record video of actual test proceedings (Actual test process demonstrated and explained in detail in the video.) Hypothesis under test: Using metered findings with a single AD200 power pack driving either a single AD200 (200 watt-second output) bare bulb or a single AD360 (360 watt-second) bare bulb- is there evidence for a higher light output from the larger xenon flash tube? Experimental Setup: A single, non-modified, fully charged AD200 power pack, attached to the previously modified Evolv 200 twin-head adapter, to allow both bulbs to function when triggered; mounted on a fixed light stand, and set to the output parameters indicated in each bracket set below. The light meter, a Gossen DigiSky flash-capable meter, updated to the latest available firmware, fully charged and connected via a PC-to-3.5mm cable to the flash input of the AD200 power pack, as per the manufacturer's recommendation. This meter was then mounted in the position indicated relative to each bare bulb, at exactly the same distance for each test performed. The meter was set to 1/125 second and ISO 100 for all tests. The settings used were derived from official manufacturer's tables recommended for the test distance employed. Each test firing was conducted 3-4 times, with the findings mean-averaged. The averaged findings were then systematically recorded for each bracket set. A single ambient background 350 milliwatt white LED shielded lamp at 8 feet distance from the test bed remained constantly illuminated throughout the testing period. All other light sources were extinguished throughout the testing period. Findings: 1) 200 w/s div 128 = 1.5625 w/s output. 360 w/s div 128 = 2.8125 w/s output. Using 1/128 output power, at 6" from bulb surface, perpendicular to the major axis of the bulb longitudinally, we observe the following recommended f-stop value as recorded by the Gossen Digisky light meter synchronized in flash mode, using the following std. settings: ISO 100, Shutter speed 1/125 second: For the AD200 bare bulb - f5.6, bulb recycle time: 0.15 sec For the AD360 bare bulb - f8, bulb recycle time: 0.25 sec 2) 200 w/s div 64 = 3.125 w/s output. 360 w/s div 64 = 5.625 w/s output. Using 1/64 output power, at 6" from bulb surface, perpendicular to the major axis of the bulb longitudinally, we observe the following recommended f-stop value as recorded by the Gossen Digisky light meter synchronized in flash mode, using the following std. settings: ISO 100, Shutter speed 1/125 second: For the AD200 bare bulb - f8, bulb recycle time: 0.25 sec For the AD360 bare bulb - f11, bulb recycle time: 0.35 sec 3) 200 w/s div 32 = 6.2500 w/s output. 360 w/s div 32 = 11.2500 w/s output. Using 1/32 output power, at 6" from bulb surface, perpendicular to the major axis of the bulb longitudinally, we observe the following recommended f-stop value as recorded by the Gossen Digisky light meter synchronized in flash mode, using the following std. settings: ISO 100, Shutter speed 1/125 second: For the AD200 bare bulb - f11, bulb recycle time: 0.35 sec For the AD360 bare bulb - f16, bulb recycle time: 0.45 sec 4) 200 w/s div 16 = 12.5000 w/s output. 360 w/s div 16 = 22.5000 w/s output. Using 1/16 output power, at 6" from bulb surface, perpendicular to the major axis of the bulb longitudinally, we observe the following recommended f-stop value as recorded by the Gossen Digisky light meter synchronized in flash mode, using the following std. settings: ISO 100, Shutter speed 1/125 second: For the AD200 bare bulb - f16, bulb recycle time: 0.40 sec For the AD360 bare bulb - f22, bulb recycle time: 0.55 sec For the rest of the story, please read my public comment below!
