I bought 8 green laser diode modules from a vendor on Aliexpress.
The diodes were speced at 2.8V - 5V operating voltage. available in 10 mw and 20mw
I asked if 5mW could be supplied. they said "yes".
When the diodes arrived, they had a sticker on the outside of a antistatic bag, stating "3.3V 1amp", instead of the 2.8V to 5V.
Our power pack produces 5V so we couldn't use the power back and now temporarily are using 6 x AA batteries @ 3Vs to power 4 lasers.
Because of the current of 4amps for the set, the lasers kill the batteries in about 30 or 40 minutes.
I expected a current draw of 300ma to 500 ma each
Can anybody tell me what the high current suggests..... Is it just cheap componentry... the lasers were about $30 each.
Because of the high current and the incorrect voltage, they are useless for our purposes.. But I'd like to know if we had been dumped with a cheap product.
