@koyotee
put away your personal problems with me.... ;)
see what i am talking of?
Lumens | Ampere | fV | Watt | W into heat |
1500 Lm | 2,25 | 6,2 | 13,95 | 10,4625 |
3000 Lm | 5,5 | 6,8 | 37,4 | 28,05 |
4000 Lm | 10 | 7,4 | 74 | 55,5 |
2x1500 Lm (3k) | 27,9 | 20,925 | ||
3x1500 Lm (4,5k) | 41,85 | 31,3875 |
... and thats only the cunsumed electrical Wattage.
Heat is usually generated the more than the Wattage is (have to find a formula)...
Edit: found a Cree document...
. To be conservative, assume LEDs convert 25% of the input power to light and output 75% of the input power as heat.-> added to my chart above
