My tree lights use metal halide bulbs and I love them! Having a light on outside is proven to be more effective than extre locks. Sometimes keeping lights on can be more effective than having an alarm system.
I noticed that too, I think it's more to load the metal halide bulbs harder by making arc tubes smaller for effective vapor pressure, in bid to bump up their general efficiency, by forcing even more halide molecules to participate into light generation. Ceramic metal halide bulbs (I have a few 35 - 39 watts CMH bulbs for my modified Halogen spotlight), on the other hand, are loaded even harder which I also can notice when compared to the regular car headlight HID bulbs and general industrial metal halide bulbs (and ceramic arc tube being loaded twice as harder compared to the classic larger Quartz arc tube of course results in better CRI - the same can be said for smaller Quartz arc tube version, to an extent, therefore CRI 80+ Quartz metal halide bulbs now also exist).
Wow, that's a clear light. Much more natural than the old bluish green. The light looks closer to the ceramic metal halide bulbs used for grow lights, the arc tube in those looks like an HPS arc tube, but the light it gives off is very close to the sun.
They make the arc tube smaller to reduce light output over a long period of time and lifespan, so LEDs look better on paper and in practice. GE has been doing this for a long time, since the late 90s. A real shame.
My initial thought on the smaller arc tube was that it allowed them to get away with reducing the mercury content, but my knowledge on arc tubes is virtually nil.

Can you start back turning the lights off on camera it is very interesting to see them glow down

Are they pulse start or probe start
@@justinmedley2580 this one is probe
@@vintagefancollector1436 do they make pulse start 250w metal halide bulbs
@@justinmedley2580 yes, pulse is available in every probe start wattage.

Nice score on those bulbs! Can’t wait to see the floodlight in a video!
What happens if you bust the bulb and the arc tube is exposed?
The bulb would still function with the arc tube exposed however, harmful UV will be able to escape with the envelope missing.
@@Parrot175 can you even touch the arc tube if the glass of the bulb were to break.
@@Parrot175 if it was burning the uv rays would be exposed?
Wow realy cool bulb
now high pressure sodium of GE
Nice MH bulbs
These bulbs are definitely still better than LED bulbs still even though these are more than likely Made in China
Something is up with your camera because there is some smearing and ghosting.
That could be true, or it might be the lighting he is using that’s eol
Carefull with radiation out of visible spectr
Made in hungari was replaced by made in China
Better than to stop producing them forever
LEDs are better
Then why are you here? Weak bait
LEDs are trash
