Advice on Creating a Lighting System

[lonepal]

Hi;

I plan to create a special lighting system for my macro Works.
I will use the system with Mitutoyo M Plan lenses.

I want to use this type of leds;

Anyone has an idea if it is a good choice or are there better leds?

Thanks.

Those should offer great color rendition but the output is very low for your intended use. You would need to use multiple pieces to get a decent light output. Depending on your intended light "design" this might not be desirable.

Hi Charles!

Thanks for the comment.
Yes I realized that the output values are very low like 30 lumens.

Do you think it is not enough for illuminating very small objects?

I use Ikea Jansjö lamps and their output is like 75lm according to their web-site.

Lumens are not a good measure of the luminous intensity of a light source; the proper unit would be the candela. An example is given in the Wikipedia article describing the candela. See the examples section. A 1700 lumen source radiating energy in all directions would have a luminous intensity of 135 cd whereas if the output is focused into a 20 degree beam, the luminous intensity would be 18,000 cd.
