SST-70 X LED
• Typical efficacy 162 lm/W at 700 mA, (6V)*
• High Brightness Cool white LED with maximum output in excess of 3,200 lm
• Available in 6500K, 70 CRI (typical) color point
• Compact monolithic emitter ideal for directional lighting applications with high
uniformity
• Rated and targeted at 85 °C
• Maximum drive current: 5250 mA (6V) ,2625 mA (12V)
Looking at the SST70 LED performance table,
• Typical efficiency of 162lm/W (6V) at 700mA
There is something like this. 700mA and 6V here
What does it mean?
In the case of CREE, it is easy to simply find lumens per watt from a performance table.
For XHP70, if you do 3022 lumens divided by 32W, you can see that the efficiency per 1W is 125 lumens. A typical 15W 18650 battery gives 1875 lumens.
However, in the case of the Luminous SST70, it is difficult to calculate the efficiency per watt because there is a condition of 700mA 6V. I don’t know how many lumens come out when using one 15W 18650 battery.
Are there any gentlemen who know the correct answer?
