I have a question among you guys, LED master (or more experienced LED user).
I compared my lux V (WX1T i believe), driven with BB (not sure drive current, most likely 500 or 667 mA) against my lux III (TWOK for sure), driven with 1 amps driver and i noticed something weird.
Both of them register approximately similar overall light output. the lux III has 1.40 lux while the lux V has 1.41~1.42 lux. Does the result is as expected?
(oh btw, overall meaning the ceiling bounce test, which explains why the reading is very low )
I measure the current draw from lithium R battery and got the following reading:
lux III driver drains ~1.2 amps while the lux V BB drains ~2 amps.
based on the readings,, what would be the point of using lux V then? It drains more power, gives flood beam and only a tiny bit more output. Is there something i am missing here?
assume the BB has 65% ~70% eff (since 3.6 V in, 6.7 Vout) which result in current out 700 mA, approx. The lux V should put out about 140 lumens.
now, assume the other driver is a linear driver (which it should be, at this input). So the lux III is driven at about 1.2 amps.
that makes it output 87 * 1.2 (approximate number for 1.2 amp drive compared to 700 mA) = 104 lumens?
I am sure my assumption might be off, but the W should perform at least 1.5 times better than the overdriven lux III right?
i am not sure if i am clear enough, but it is a tiring day so
thanks for the help beforehand, anyhow
