Where does one find a clear SB MV lamp like this? What is the cost?

I probably paid about US$25 for set of 4 at ebay.

Question...is the incandescent filament removed from the circuit once the lamp has reached full brightness?

Nope. It's the ballast. Without it the lamp will explode from a surge of high current.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

Very cool bulb. I have a bunch of 160 watt frosted SBMVs and the only thing they will fit is a large table lamp in my living room!

I've always wondered about this... In a 160w SBMV for example, do the filament and arc tube each use 80w totalling 160w or are they each 160w somehow only totalling 160w of electricity consumed? I'm confused about this.

Nothing like the beautiful cool white light of a coated Mercury Vapor lamp and the soothing hum of it's magnetic ballast.

@tmcdllr: It is about 1/2 power in MV and 1/2 in incandescent. But the total efficacy is lower compare to if you connect in series (how 230V versions are arranged) corresponding separate lamps, as there are conflicting requirement for the outer atmosphere: MV ask for really low pressure fill (to minimize arctube thermal losses), while the filament need high pressure (nearly an atmosphere) fill in order to rise it's efficacy (the gas make a barrier towards tungsten evaporation, so the filament might run hotter, so with higher efficacy, when the pressure is higher) So an compromise is made, what mean the pressure is too high for optimal MV operation and loo low for optimal incandescent operation.
On 120V lamps the efficacy is lower even further, as the arctube has to be designed for lower arc voltage (~65V), what make nonradiating cathode-fall dissipation more significant (~15..20%) then on regular 130V MV (~8..10%).

rjluna2, do your lamps blink off & on a couple of times before the arc strikes? Mine does and I wasn't sure if that was normal.

My very first word was LIGHT!

Did you mean the hot restrike? Due to the bimetallic strip, it doesn't blink off/on like the regular mercury lamp. I guess my bulb have a better quality bimetallic strip I have to wait about 5 minutes when the bimetallic strip cools down before it restrike. The strip reconnect the preheat filament inside the arc tube to warm up the mercury inside the arc. The 120 Volts is not enough to do cold/hot strike across the arc tube. It almost behaves like hot cathode mercury vapor rectifier tube, only in AC circuit.

Does it make sense to you?

Pretty, please no more Chinese failure.

When mine is turned on (cold), only the incandescent filament is lit for about two minutes until the bimetallic switch opens & closes a couple of times then the arc finally strikes.

I did at one point to check the wattage with kill-a-watt meter and found that it was running 212 Watts intially. Then when the Mercury arc tube is running full power, I get around 160 Watts.

I am thinking that this one may be 200 Watts filament and 50 Watt arc tube

Before the arc tube is struck, the filiment runs at a higher voltage, driving its wattage up. You also have the wattage of the preheating filaments.

So why not use a halogen capsule instead of an open filament so that each can operate at optimum temperature? I've seen them once or twice. I know it'd cost more, but not by much.

@Xytrell: I think there is one big reason: Cost.
To make it reasonably profitable, such lamp would cost way more then MH lamp, so not much people would buy it in the MH and CFL competition, as it is rather inefficient and has too harsh light in most western's perception. Far east market is a bit unique, where uncoated blended MV light is perceived as so luxurious, then people are ready to pay both the purchase as well as the electricity cost for running them, so development continue for them. But with such price it would be unsellable in other parts of the world, so it is even not offered.

UV does not pass through glass so you should be ok, uv lamps use quartz and these must not be looked at or contact with skin, burning.

Interested in the history of electric lighting and incandescent in particular and neon glow lamps.

The long wave UV-A pass through the glass. These are the dangerous med UV-B and short UV-C that don't passes the glass.
UV-A can damage the eyes. Also, visible light can also damage the eyes if staring into for a long time.

Yes these clear ones emit more UV than the coated ones. If you put this in a fitting with a pollycarbonate cover it would yellow it in no time... Nice lamp RJ

The difference in UV-A emission between the clear and the phosphored ones is negligible.

Thanks, Danny. This specimen is now sadly burned out. See at Burned out Self-Ballast Clear Mercury Vapor Light Bulb

Merrily, I have replaced with another 160W Clear Self Ballast Mercury Lamp for the lovely consumption

Pretty, please no more Chinese failure.

Clear mercs are lush but self ballasted examples are always a treat to watch running up and hot restriking!

I have an 160w Iwasaki and noname Chinese clear MV lamp.

My main area of interest is vintage fluorescent and mercury lamps. Always interested in doing lamp trades - just let me know! Smiley

Just an additional note to the UV: The differences in the UV emission between different lamp types do not come, as Dor already wrote, from the presence or lack of a phosphor, but from the differences in the outer bulb glass composition and thickness (and that vary a lot).
