Macro flash

Compatible with lenses that accept 58mm filters.
I use this macro flash with a Canon 100mm 2.8 macro USM 1:1 +macro extension tubes. The light is strong, enough to be use camera from hand. You can take pictures at 1/100, F6, and ISO 400 f6 in house.
Generated light is much superior to the macro ring with 72 LEDs.

Specs of the macro flash ring:
Total current drain ~ 2.2Ah at 7.4V, (1x NB-2LH 7.4V/1200mAh LI-IO battery or indoor use 7V DC adapter with 2Ah)
Temperature after 10 minutes is ~55-60 °C
It is very lightweight: macro flash ring 102gr
The circuit is designed to have two phases of light, full or half (only half of the LEDs light up)
Range is 5-20cm, ideal for super macro.
