I love the Ceramic Metal Halide bulb, I have it in my modified Cyclops Thor Colossus Halogen spotlight (the 35 - 39 Watts Ceramic Metal Halide bulb apparently works fine with the 35 Watts automotive digital metal halide inverter ballast, I made sure it's AC output though - it's definitely squarewave AC which is what the bulb I used wants). Nicer and way more efficient than the original Halogen bulb, for sure. It lasts forever so I figured I'd give it a try.
I have a couple CMH lamps. These things are bloody awesome for video work... Also, get these lamps under a blacklight and the outer jackets glow a light blue because of the UV block they have on their outer jackets.
I had an ingenious idea that I'm gonna probably document on my other channel. It includes automotive ballasts, a pair of Quartz metal halide lamps, a beefy lithium battery and probably an explosion or two.
I have put in a lot of metal halide lamps most of them where 400 watts but I have seen as small as 100 watt but never anything that small. There really kinda cute.
The arc tube on the 150w one looks rather out of proportion compared to the 20w arc tube lost in its outer shell. Aluminium oxide is held together in a giant covalent lattice and individual atoms are bonded with polar covalent bonds, so it's made of strong stuff!
It is silly small when you compare it with the 150w lamp. At 83 lm/w it's still quite efficient too. I'd rather have a load of these lighting my shop than LED :)
I have a couple of Sylvania Powerball self-ballasted 24W floodlamps, only one of which I have run up. They are designed to replace a 75w PAR30NF halogen floodlamp and provide improved colour rendering and longer service life. Unfortunately they are no longer in production for the US market; however I did manage to pick up these two for $5.
Those "CDM" lamps are kind of rare and expensive here in Canada. In fact any low wattage M.H lamp I find are pricey, as in $50-$80 each for a 20W "PAR-20" M.H lamp... The hospital I work at had a few hundred of those for wall-wash lights and in track fixtures but due to price they are being retrofitted to 7W LED
I bought a used track fixture on eBay (35W 3000K G12 Base) Is there any tips or tricks on how to remove the G12 lamp from the socket with out breaking the lamp? I want to remove it to get a good look it. It looks like there is two metal tabs that have to clear the bottom of the base before the lamp can be removed but I can't get my hand in there and bend both at the same time. So there has to be another way to get the lamp out? PS: In the USA these small Metal Halide lamps are really pricey (A New lamp costs more then I paid for the whole fixture). I guess they never really caught on in the US and most of them got replaced with crappy LEDs
A system of ballast "high intensity discharge" used in cars would be 35 watts, could ascend one metal halide lamp, or would a difference? example. Xenon of the ignition at 25 kV and metal vapor at 4.5 kV.
Ususally you'd use one of these itty bitty little halide lamps in something like a down light. Somewhere like a shop display where you want a nice en colour temperature that's consistent across all your lamps. Also. These lamps are generally around 3,000 to 5,000 kelvin in colour temperature. This varies with age though as they lose intensity and shift a little in colour as they age.
By the way, your claim that quartz is used for an outer envelope is wrong. Quartz (like ceramic) is used as a super tough material for making the arc tube itself. The outer glass envelope of a bulb like this is made of normal glass. That blue glow is actually the glass fluorescing. Glass will fluoresce when exposed to x-rays or to extremely short wave UV rays.
The larger lamps have their outer envelope made from hard glass but there is no way hard glass would survive so close to the arc tube in a compact lamp. If you still don't believe me then check out GE's own data sheet that list the outer bulb material as UV block quartz: www.gelighting.com/LightingWeb/emea/images/ConstantColor_CMH_G12_Lamps_Data_sheet_EN_tcm181-12593.pdf
FrontSideBus Still pretty sure that it's a hard glass. At only 20 watts or 35 watts, it won't crack a glass envelope (though some of those 75 or 100 watt compact bulbs are a different story). Usually the size of the envelope is specifically selected (using optimization formulas involving the science of thermodynamics) so it will be small enough to not waste space, but not so small as to be damaged by the heat.

I use a 20w cmh MR16 for a flag light in a retro-fitted 50w halogen spot light. Its been going strong for 3 years. Love these lights.

That's pretty cool :) I had no idea they made them so tiny.
I like 20 watt metalhalide lamps.
Using 20 watt fluorescenc ballast you can turn them on.
They will wirm up to 100% : )

You can get 108lm/W from a good quality XMH lamp, but then they're even more expensive than these are, and only good for 5,000 hours.

These must be one of the most popular forms of shop & display lighting in the UK with the most common wattages being 35, 70 and 150w!
Small metal halide lamps
I found out there is also a 10 watt Metal Halide lamp but don't know where to buy it
expensive at $68.44

Aww baby metal halide lamps
I know the metal halides get very hot, but not as terrible as incandescent or halogen. Though, do the 20w versions get hot?
Where can I get tiny MH bulbs for cheap? They are more expensive than the standard size ones (easilly $40 for 20w, instead of $25 for 100w).
Keep an eye out on eBay. They routinely appear cheap. At least on UK eBay that is...
Can i grow plants with this CMH 70W
A system of ballast "high intensity discharge" used in cars would be 35 watts, could ascend one metal halide lamp, or would a difference? example. Xenon of the ignition at 25 kV and metal vapor at 4.5 kV.
I have used it that way in my portable HID spotlight - it works fine, but FYI, it may refuse to relight when hot which was in my case.

where are these tiny 20W metal halides used? what kolor temperature are these Metal halides?

Where can I buy one ?
Try eBay.
@@FrontSideBus thanks 😊
@@FrontSideBus I searched on eBay but it says search not found : (
