OSRAM DULUX POCKET

OSRAM DULUX POCKET

This is Osram's pocket cfl using two AA batteries. I use it for outdoor-activities like camping. One issue I have is, that it gets easily switched on while carrying around. At least it delivers a nice bright light.

I have the same one but black. Mine draws under 2 watts so the tube is underdriven.

If mine is running a while the tube shows signs of mercury-migration.

I like how that looks! It looks like it has a 5watt PL bulb in it even though there is not a PL bulb in it.

I had one of those but lost it, they are really cool and bright. Where can I find one of these? I want one.

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

This lamps are not produced anymore - maybe you can get one at EBAY. I bought mine some years ago in a discount-shop for about 5$.

I have my own version of pocket fluorescent lantern at Phorm Concept + Design Light Voyager

Pretty, please no more Chinese failure.

I think for these applications LED do better job, both in efficacy and lifetime...

The older ones made before 1997 are the best in terms of efficiency and brightness I would say the tube was driven at 80%. The ones made later, I bought another one in 2005 were crap. The tube was under driven and cannot start after some use because it was so under driven. But if you open one up...there's a trimmer pot or an adjustable knob where I think the power can be adjusted.

@Prismatic: If your lamp in your Dulux Pocket, shows a mercury migration after a while, this means that either the tube rectifying, or, if the tube already operates directly from the DC (Seems to be more correct, based of the size of the lantern), so there is a manufacturing error in your lamp.

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.

@imj: The biggest problem with proper tube driving is, then for two AA cells is 2W already way too much load, while the lamp would ask for 5W and the ballast have at best 80% efficiency, what in total would mean ~6W, so 2A from the 3V battery - quite a lot even for D cells and totally impossible for AA...
And i would not play a lot with the trimmer: If you "adjust the power" above the designed level (this is usually, where it is set from factory), the ballast efficiency drop as well.
And as a consequence at first batteries would be overloaded way more, so die way sooner.
And what is more important, the inverter may "enter" the thermally unstable mode, where the transistor in the ballast would overheat. This thermal instability is caused by the temperature dependence of the bipolar current gain (it rises with the die temperature) and the fact, then the inverter power (and then mainly transistor switching losses) rises with the transistor's gain, what make a runaway positive feedback. The power dependency on the NPN gain the reason for the trimmer - to calibrate out the piece-to-piece variation of the NPN parameters.

I've wanted one of these for quite a while. Months ago I saved a search for them on eBay, and so far not a single one has ever turned up! I wonder if it would be possible to MacGyver a 5 watt PL out of it's base and directly solder it on there, should the bulb ever need to be replaced?

Edit: Make that over a year I've had a search for these saved on eBay. Still not a single one has ever turned up!

I have the Radio Shack version of this and it's quite bright.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.

Unfortunately cold starting without programmed preheating the cahodes. So it was expensive product with not so much long life.
