    Possibility for portable battery-powered Ceramic Metal Halide fixture

    Final thing I want to add, regarding the ceramic metal halide bulbs with UV glow bottle starter inside, hot restrike feature may not work with car headlight HID inverter ballast due to DC current used during ignition and warmup in a particular polarity in the socket, so you may want to flip the...

    365nm UV Flashlight ... since I can actually see that wavelength! ;-)

    Pardon the necropost, however, I have long since discovered that I am tetrachromatic despite being a dude (it's much more common in women, apparently), I could see the UV as well as Infrared light, even with unaltered eyes, to me 365 nanometers UV looks like a very harsh hue of purple, even with...

    Possibility for portable battery-powered Ceramic Metal Halide fixture

    I just discovered something about the Sylvania Osram Powerball CMH bulb that's in my spotlight; while General Electric ConstantColor CMH bulbs can't be hot restruck, this bulb restruck instantly, even with the ceramic arc tube still glowing red hot. So, if you want to use ceramic metal halide...

    Possibility for portable battery-powered Ceramic Metal Halide fixture

    I think I figured out why the Osram Powerball ceramic metal halide bulb fluorescences hot pink under the Blacklight lamp, it turns out it's due to a particular salt used in the 3,000 Kelvins version (I wonder if it's the same for 4,200 Kelvins version), apparently.

    Curiosity got the best of me; will Ceramic Metal Halide do in modified Cyclops Thor?

    And yes the CMH setup here is as bright as the original H4 140 Watts Halogen bulb, but far more efficient. 3,000 Kelvin version of CMH is just like the original Halogen bulb in term of color rendition that we usually see with the Halogen bulbs. 4,200 Kelvin version is hard to find. Maybe it was...

    Curiosity got the best of me; will Ceramic Metal Halide do in modified Cyclops Thor?

    All done. I have been putting off ceramic metal halide bulb mod for far too long, until last year, that I decided to just grab the ceramic metal halide bulb setup and it works (had to get better HID ballast, especially Hylux A2088, so CMH bulbs completely warm up best). Both 39 Watts Sylvania...

    Possibility for portable battery-powered Ceramic Metal Halide fixture

    IF anyone dare to use the same ceramic metal halide bulb setup in the Cyclops Thor Colossus Halogen spotlight as my spotlight or just a basis for any HID spotlights, please use quality AC ballast, preferably computer controlled internally, and Hylux A2088 is excellent and it lights up the 39...

    Muyshondt has really disappointed. I will never buy from him again. Am I wrong here?

    Well, if a flashlight is defective, I'd keep it, as I got my money's worth already; I just simply repair it (some flashlight host bodies are actually quite decent when fixed), or just go crazy with customization.

    Possibility for portable battery-powered Ceramic Metal Halide fixture

    Apparently I am thinking that Powerball Ceramic Metal Halide bulb has a YAG ceramic arc tube - I decided to see if the bulb indeed has the UV killer dopants in the outer Quartz envelope (out of curiosity), which as you can see in the picture, the answer is an obvious yes. However, I spotted the...

    Bioenno Power LiFePO4 cell pack question

    Yep, I went with the Lithium Iron Phosphate battery pack as I knew I would be keeping the same modified Cyclops Thor Colossus Halogen spotlight for a long time, so it made sense to spend a bit more on a decent 12 Volts DC battery pack that would outlast the original Lead-acid batteries that I...

    Possibility for portable battery-powered Ceramic Metal Halide fixture

    FYI, 4,200 Kelvins Ceramic Metal Halide bulbs are apparently very hard to find, while I can easily find and buy 3,000 Kelvins CMH bulbs. I wonder why. 🤔

    Bioenno Power LiFePO4 cell pack question

    Here to report after six years of owning the same Bioenno Power battery pack, it is definitely 100% worth the money. I still have good runtime with it, although knocked down to 1 1/2 hours instead of the original 2 hours because of the metal halide bulb and ballast change; I am currently using...

    Possibility for portable battery-powered Ceramic Metal Halide fixture

    And the ceramic arc tube shape apparently matters a lot - GE ConstantColor CMH bulb has a tubular ceramic arc tube (a bit like the usual high pressure Sodium bulb) which doesn't really favor some reflectors as you can see in the beamshot pictures below. I prefer the Osram Powerball CMH bulb more...

    Possibility for portable battery-powered Ceramic Metal Halide fixture

    Got the Sylvania / Osram Powerball ceramic metal halide bulb from Amazon in the mail, I immediately installed it in my modified Cyclops Thor Colossus spotlight, it surprisingly warmed up instantly (via Hylux 35 Watts A2088 conputerized inverter ballast which has expedited warmup feature), so I...

    Possibility for portable battery-powered Ceramic Metal Halide fixture

    Ordered the Osram Powerball Ceramic Metal Halide bulb to try out to see if spherical ceramic arc tube makes any difference for the reflector in the Cyclops Thor Colossus Halogen spotlight. At least I installed the G8.5 Halogen bulb socket meant for HID bulb (rated for the ignition voltage -...
