If there is no urgency in recovering the money you might hold on to it for a bit and see if an SM-LUX-HL frame only, comes up for sale at a good price.
A good point. :) never know what might pop up for a reasonable price.

Re: Leitz sm lux bulb replacement?

Just as an update: seller was fantastic about the whole thing and refunded the full price, plus allowed me to keep the part. Can't ask any more than that. There are some dodgy geezers on ebay, but luckily this was not one of them. :) I guess i have a lampholder for sale then? i really can't find any...

Re: Leitz sm lux bulb replacement?

As ungainly as it may be, is the longer one able to work if pushed into place until the bulb is in the right place - that is with some of the holder sticking-out of the base rather than flush like the original? Just a thought, but maybe a stupid one.... John B. sorry John, missed this post. :P yeah...

Re: Leitz sm lux bulb replacement?

yeah, true. I would think the options 2 or 3 will be the better bet, judging by the way the holder fits in, to adapt to the new lighting will involve more than just electrical parts, the internal tube, and reflecting pieces, are in the way, or wrongly 'shaped' to accept the new lampholder anyhow.

Re: Leitz sm lux bulb replacement?

I did not notice the difference in the length nor the electrical connection points. It does seem to exist, though not a straight swop.

here is the two holders side by side - you can see the difference. Physically the longer one will not fit into the same hole.

Much better colours. Very nice.

Re: What interesting things I can look for to observe under the microscope?

Mineral water contains chemicals. The composition of this water may be very different from that of surface water and the water we drink.

Re: Leitz sm lux bulb replacement?

If you exceed the voltage you will burn the bulb out very quickly. Can you check if you did? Would be a easy fix if so. :) I wouldn't know how to check that kind of thing to be honest. I know that the scope itself runs off a UK plug (240V/230V i think) rather than me having to convert it with a tra...

Re: Leitz sm lux bulb replacement?

I'm still curious about that 20W holder that 75RR linked though - it looks like it might be a good upgrade, although it would be cool to find a UK based listing.

I at least know that the bulb holder would fit if i do find one in the uk - so i'll keep an eye out. :)

Re: What interesting things I can look for to observe under the microscope?

Agree. I too find moss to be a good source of water critters. I pull up a few chunks of moss from the ground and put it in a small container with a splash of rainwater- bring it indoors and maybe add a splash of bottled mineral water (hoping to avoid tap water chemicals) Then i just take a drop with...

Hi, My sm lux recently blew its bulb, so while looking for a replacement i've found the exact bulb difficult to locate.
