These LED units are rechargeable keychain lights which I purchase in bulk lots to modify into focusing light units for macro photography. They work very well for the intended use, and come in very handy when an extra light source is needed to help with focusing on a subject in darkly lit areas.

They also work very well for lighting a subject when engaged in night macro. They come in two modifications. One to suit the Meike MK-320 flash, and the other to suit the Godox V-350 flash units. These are available for $10.00 each and can be included at no extra postage cost with your diffuser if required.

UPDATE!

I have a few totally radical new design options that include some rechargeable battery packs, to improve the performance of these LED lights. I have also designed a couple of new mount options for the LED’s so that they sit further into the diffuser, concentrating the light.
I have sourced some lightweight Rechargeable Battery Packs that will run the lights on full power for the whole macro shoot, and more. Up to 24 hours if needed to. These are now listed in Accessories, and are available to order on the order page.
