This is an example only:

Because I live in Poland, this example.
But you can Google in your own country England?
Star LED 3 Watts.

It is not UV only , but very bright light on maximum output can be harmful as well , better be carefull ..

@ Amoeba If you convert to LED be very carefull as well for your eyesight! I think that is a must that you can regulate the light, esspecially some are giving UV light as well... @ Bob That Biolam travel microscope I have never seen before, awesome. My Biolam is also fitted in a transportcase , but ...

Thank you for the link which I will take a look at. In the meantime,the fitting seems to be B15 so I was wondering whether as a direct replacement one of these might work as a quick and dirty drop-in replacement? https://www.ebay.co.uk/itm/272969921871?hash=item3f8e46754f Obviously, as with the ori...

This is what I am using in my Lomo OI-35.
It fits perfectly in the lampholder,now with Star LED.
To be honest I did not make it myself, but a friend of mine who is an electician...
The LED on print is coming from Conrad.
But made according that article.

Well I managed to release the faulty bulb! It turns out that the aluminium piece that fits into the lamp barrel has to be rotated and slackened off the lamp holder before the bulb can be removed. The penetrating fluid may have helped the inner and outer metal pieces to come apart. An interesting ar...

Do you mean this one as the portable Biolam set Bob?
This is mine since 1974,Biolam D1.
Almost everything in the case except the binocular head and the OI 35 lighting.
Crosstable CT-12, monotube, darkfieldcondensor, 8 objectives, oculars, dustcover, camera adapter...

I second that completely, true story, Bob
That's why I like Lomo Biolam as well.
Ben.

What is also a good idea is to buy a secondhand Olympus Koehler light, see this:
viewtopic.php?f=24&t=14305
Which you can probably convert to LED as well.

@ Amoeba: A lot of Lomo produscts are coming from Russia, Belarus or Ukrain, so due to the Russian invasion I will not order anything from Russia or Belarus. For Ukrain is different, but I am affraid that at the moment they cannot deliver, lots of families lost everything. So maybe you can find in G...

You have a very nice scope there Amoeba, the rotating table is a very big plus. For myself I have a Lomo Biolam D1 with a square table and CT-12 crosstable. For Lomo are lots and lots accesoires available, I should defenitly keep it and 30 pounds is a steel. Like Apochronaut pointed out objectives a...

Never to old to learn. Thanks Apochronaut .
Ben.

Ok, never heard about quartz coverslips, seems I am getting old ...

Thanks for the info zzffnn, keep that in mind.
Ben.

Ok, thanks I will remember that...

Thanks Pete, yes I am glad that it works fine now, it was a new experience and not that easy because about everything was stuck, starting with the lenscap to dismantle.
Hope to find one day a nice 60x waterimmersion to complete it, have the 40x waterimmersion as well.

Finally, after taking everything apart, cleaned it thoroughly , put several marks and making a lot of photo's , relubed it with special grease for instruments, replaced all the parts back again. Now working fine. I thank everybody on this forum for the tips as well as Mr. Sterrenburg on Micscape for...

Thanks for the welcome, my first post is in the chapter Microscopes and objectives, problems with my 85/1.0 waterimmersion...

I was able to remove the lenscap by applying heat from a hairdryer on the lowest heat position and checked temperature with a digital meter, so on exact 40 degrees Celsius I was able to loosen the lenscap .
Tomorrow will go further ....

Thanks for the advise...
Good tips ...
Ben.

Yes I will do so if I take it apart, better more photo's than less.

OK, thanks.
For the moment I make not yet the decision to take it apart completely,but for now I think I have enough information.

Thanks Patta for the reply, as from now with a drop of oil the coverslip ring is working again, so far so good. But I wonder leave it as it is, or take the objective apart for fully regrease? My problem with this objective that the lenscap or tip as you name it , will not come loose, or does it need...

Hello Apochronaut, Thanks for the information, I will try it with thin oil. Yes I am familiar with the Soviet grease used in their microscopes, around 2014 I found my Biolam miscroscope back and the first thing I noticed that course and fine focus was completely seized. So then I took it apart ,clea...

Hello, my name is Ben and I am new here on the forum, yesterday I have filled in my introduction. Now I have the following question, I have the Lomo 85x/1.0 waterimmersion objective with adjustable coverglassring which is really stuck, not moveable. So I have found this for solution: http://www.micr...

Hi, my name is Ben and I started my microscopehobby in the seventies, for a long time I did not use my microscope,but now I am retired and I want to spend more time into this hobby. I have a Lomo Biolam D1 misroscope with monotube as well as binocularhead, normal and darkfieldcondensor, Lomo Koehler...
