What is this fly with legs like a flea?
A quote from 'Rik and the Beanstalk'

'Flea Fly Foe Flung' lol.

When flies turn rogue, really annoying, in your face. Like they have a death wish,
I have heard them called 'D*mn Flies'.
This has got to be one of those D*mn Flies!

Re: How good are alternatives (clones) to Mitutoyo lenses

My spidey-senses are tingling. I am getting a bad feeling about this.
Clone on the outside, but a few faulty genes on the inside.
Hope I am wrong though.
I do like a bargain

Re: Tungsten to LED Microscope conversion

Maybe if you were running it 24/7 in a lab setting it would be more of a concern The future for halogen bulbs is looking dim. Already banned in some countries. It's the cumulative effects of all those energy hogging bulbs burning. Messing up the thermostat on polar bears outdoor fridges. After a sh...

Re: Tungsten to LED Microscope conversion

Excellent advice given above Thanks for that ModelZ. Today I ordered up some discrete components as well as a pwm controller. Will use the existing lighting transformer to provide the power. A bit of a test and tweak with components. For fun, I ordered more stuff than I need. The LEDs presentartion...

Re: Tungsten to LED Microscope conversion

Thanks to all who gave their thoughts and help. Well today a man showed up with a Nikon in a box. I had bought this with trepidation. I had scoured the photos and even got the seller to take some more. It was a 'Spares or Repair' Scope. I wanted any visual clues as to condition. A good sign I though...

Re: Tungsten to LED Microscope conversion

LEDs are very variated Good points Pau. LED quality can vary widely especially bargain bin lots from the far east. They are also prone to fade over time. I agree with using high CRI units. I like to keep some Lee/Rosco gels to balance out speedlights matching other light sources. I haven't much exp...

Re: Tungsten to LED Microscope conversion

it's a bit higher temperature then a standard halogen (3200K) Chris, I have ordered a range of 4000k - 5000k leds to test and try to give a more neutral tint. Not quite daylight. The point I was making about the 3350k Halogen bulb is that it is on the warm side. A case of in it's day that was gener...

Re: Tungsten to LED Microscope conversion

A LED conversion shouldn't be very difficult Thanks Pete, I have ordered a new halogen bulb. Light output starts to gradually fade early on with these bulb types. Bulb colour temp is 3350k, which is a bit too warm I think. 460 lumens of light output, so I would think you are right about the LED equ...

Tungsten to LED Microscope conversion

With an older type Nikon Eclipse E200 on the way. 'Older' being illumination via a 6v 20w Halogen bulb. The more recent version has an LED source. Looking twice at the price of this 'LED swap out upgrade' there was a sticker shock of $500! There must be a total of $30 in components! Now I recognise ...

Re: Nikon Microscope a couple of questions

Thanks Pete.

For the heads up!

Think I will go ahead with E200 for the moment,
Then upgrade down the line, when I sell off some surplus equipment.
The E600 is looking good good
