Burned out Self-Ballast Clear Mercury Vapor Light Bulb

Burned out Self-Ballast Clear Mercury Vapor Light Bulb


Well, gang, it is officially burned out today (2010-10-9) after about 2 years of weekend of uses.

This one was used at 160W Self Ballast Clear Mercury Vapor Light. Notice blacken on the upper part of the bulb due to filament evaporation. Here what happens when I turned on for today, a couple of brief flashes of overdriving filament as it started, then starts to warm up for a few seconds. Finally another set of brief flashes, then it went out. As you can see the picture that missing part of the filament between support to the frame. I could not find the broken filament inside the envelope, probably evaporated as it burned out

I replaced with another 160 Watts Self-Ballast Clear Mercury Vapor light and continues for another couple of years of consumption

If I understood well, it was 2 years running two nights per week, that is only 2*10*2*50=2000hours, not much for SBMV...

I used the light on three Saturdays on each month when I do my laundry that I have in my bedroom. I think that is more frequent light on that could cause shorter life along with no name bulb

Pretty, please no more Chinese failure.

The streetlight lamp rating is based on 10 burning hour per cycle, what is in your case (~100 cycles) equivalent to about 1000 rated hours as well.
And i see the filament failing, not the discharge, what suggest the overall burning time was the limiting factor.

I would guess, then some water impurity remained in the outer (due to manufacturing process defect - e.g. missing or too low dose of the phosphor getter) and this water accelerate the tungsten transfer from the filament to the outer...

Normally SBMV's should last 4000 Hours for a good qhality lamp say a Philips ML Lamp so if this lamp is a chap chinese Brand 2000 hours is not too bad

Shame, I`d love to have a clear one, great that you had a replacement though
I never dump my used lamps, just make a record of how long they ran, then they go in the `relic` box.
Then, when I`m about 80 years old, they`ll be some right old dinosaurs in there!!!!!

HI Rich

Clear SBMV Lamps are very Hard/if not impossible to come by in the UK, the only supplier was Lampspecs and when I ordered it, they had to refund me as they sold out, and were unable to get any more in, some sulliers in the USA sell Clear SBMV lamps but they refuse to ship outside the USA, however I did get a Clear Iwasaki 160w SBMV lamp as a Second Chance offer through E-bay, but it was very expensive at £40.50 plus Postage the other Clear SBMV I have is a US Philips (Westinghouse) lamp which was a swap from a fellow member for a Vintage Siemens MAT/V lamp

All the Best

HI Rich

I like the design/Construction of the Clear Discharge Lamps as you can see how they are made and the Layout, unlike the European SON, MBF/U MBI/E, and SBMV which have all Coated Bulbs OK we have the SON-T and MBI-T Lamps and if lucky the MB/U lamps but they dont seem the same as they have Tubular, Clear Bulbs except for the 1000w MB/U which Osram GEC made with a Clear Elliptical Bulb see HEREalso we can get MBI-E lamps with Clear Elliptical Bulbs too. Me I am fortunate to have MB/U Lamps in 80 watts, 125 watts, 250 watts, 400 watts and 1000 watts, the 80 and 125 wat MB/Us looks like 150/200w Filament Bulbs but have 3 pin BC caps to stop them being accidently mistaken for a Filament bulb.

All the Best

I love looking at fully run up MB/Us and MBI, (through 2 pairs of sun glasses!), you can see how the arcs behave in each lamp, and the `bowing` up of the arc, like you say, you can`t do that with coated lamps.
Love that 1KW merc

Only 2000 hrs. The clear ones are impossible to find, but now even the coated ones are hard to come by that don't cost a fortune. I've still got a good coated one I use at home, but 1000bulbs recently stopped selling them. Nobody else's got them either.

Bring SOX lamps back!!!

FYI, LED's are NOT the most efficient lighting technology available! Don't know how people keep coming to that conclusion!

I'd love a clear SBMV! At least a US SBMV can be run on a simple step-down transformer for 240v operation, unlike US ballast/lamp combinations.

@BG101: In Europe you may run US MV lamps on European ballasts:
"lamp" on "ballast"
MV75W on "MV80W"
MV100W on "SON/MH70W" without ignitor
MV175W on "SON/MH150W" without ignitor
MV250W on "MV250W"
MV400W on "MV400W"

I have a Clear SBMV lamp that was intended as a reptile lamp. They are popular for use by bug catchers and reptile keepers.

IOT_1928: SBMV lamps indeed attracts bugs very easy, but they produces a very large amount of heats and consume many power, so they would be complicated for bug zappers. UVA fluorescent lamps have better design for bug zappers.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

With such heat the lamp alone is probably an insect killer - it can burn them as they touch it

Thanks for the guide Medved - would these operate the lamps correctly? (Specifically the 100/175W as I'm interested in getting these wattages as they will have a practical use for me)

2000 hours seems VERY short to me, a waste of a MV lamp in my opinion. I thought one of the intended uses of SBMV lamps was for a long life/low maintenance installation in hard to reach places.

The SBMV have a problem with that because it is also incandescent, so have filament evaporation etc (as you see the blackening on the outer lamp)

The filamen is overdriven while the arctube is warming up and underdriven when it is fully warmed up - so SBMV is mostly wears from startup time

You can make the filament last longer by connecting the SBMV on a dimmer / on some high power series inductor HID ballast (not a step up transformer but just a plain inducor to lower the current somewhat). This will be better for the filament, but if you overdo it it will be bad for the arctube as it will blacken and fail to warm up

For hard to reach places, better use full mercury lamps and not SBMV

@BG:
The 100W MV lamp on a 70WMH/HPS ballast run exactly on the rated current (I use it that way... )
And the 175W MV on the 150MH/HPS ballast should be (according to calculations) correct as well.

Only when using existing 70W or 150W fixtures, make sure you deactivate the ignitor - it could damage the lamp (mainly during hot restrike)

@ rjluna2

I have some no name Clear SBMV. the filament seem to be overdrivin. I experimented on mine on a dimmer
adaptor for a table lamp. and this is very interesting the arc dont go out using the dimmer. set the dimmer
on 85 percent. now it not as overdrivin and the MV is more bluer.

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

Where did I can get one of this self ballasted Mercury Vapor lamps?

The light bulb is probably one of the best inventions ever! Whit out this awesome object, the history of humanity could be another!
I love HID and Fluorescent (specially SlimLine) bulbs so my collection bases on that! Please return MV/T12!

@funkybulb: The filament is on purpose a bit overdriven when the arctube haven't warmed yet, the reason is to keep the filament efficacy still reasonable (so not run it too cold) mainly after the arctube warm up and reach full voltage drop. The overdriven state is not considered as a problem, as the lamp is expected to be operated for longer hours (life rating is for 10) per start, so not spend as much cumulative time in the warmup state, so the extra cumulative wear is assumed as acceptable.

Well, gang after about 4 1/2 years of every other weekend uses the replacement bulb finally gave out. When I first turn on the light today, it lit up with incandescent light glowing. It gave a brief flash, then the incandescent light continues to burn almost a second and half then it went out (probably the filament in the arc continues to burn, but it was not enough to maintain.) Here is the result of EOL bulb:

If you opened it up very carefully, could you put a halogen capsul in between where the filament used to be? That might be a good way to fix it, if it works.

Any machine is a smoke machine if you operate it wrong enough.

I could do that, but I don't know if this would work since it has the preheat filament inside the arc tube to strike up reliablity at 120 Volts circuit. It might be also destroyed during EOL

I have a self balasted mercury lamp but its a sun tanning lamp.


You should have smashed open the outter envelope and taken the arc tube out for. Experimentation...
