Now the question is the safety to discharge at 55A for 45A max discharge battery. Looks like power consumption wise it is there.
And question about the very high efficiency of Acebeam circuit to deliver all these power to the LEDs, or it won’t get to 80k lumens.
More review will reveal the actual lumens number.
This is both scam and SAFETY issue to me.
Acebeam should make X75 takes 8x21700 battery pack and sell this battery pack at cost price to existing buyer. Feels like it is incomplete product with 4x21700 battery pack.
You mean modded direct drive lights? Sure some extreme expert modders are doing that for extreme performance. But 55A for one 21700 battery is not common.
I am not aware of any stock light that sucks 55A of juice per battery.
wow it does look a bit underwhelming at that pic, if thats how its close to reality what u see with eyes it seems its not worth it… so many lumens and not so big difference ?
i think the flashlight industry needs rules and regulations, stating a light that does 80k lumens but doesnt even hold that for even 10 seconds sounds like a ripoff to me…
700w boost driver? Maybe, but for low - med modes only. I ques its a buck driver with DD channel. To know for sure we have to know drivers output voltage. Is it so hard to measure?
Manufacturer max discharge current is still 45A, but it has higher capacity and lower internal resistance.
Although lower internal resistance will have less voltage drop hence lower current draw, I think it will still be over 45A max current to get 80k lumens OTF for 12 XHP70.2
I have not had a chance to test the X75 but from my experience with Acebeam products, having reviewed the E70, the E70 Ti and the Rider RX, they seem to deliver both on quality and reliability. I would be interested to see specific measurements on the X75 by someone who has the required equipment.
Marco at 1Lumen has been sent one recently. Cheule measured the 5000K on his calibrated PVC tube and hit 64K, Matt Smith also achieved similar. In saying this though, no reviewer is going to be able to give a proper reading since we don’t have a certified calibration light.
I measured the range tonight at 5 meters and only hit 932 meters for a split second.
Acebeam make great products, but it’s quite common to not achieve their specs, even the range falls short. I reviewed the Rider RX and E70 Mini and this was the case for me and everyone else.
I have always known that the 80k lumens if real (?) Were only a dream of 3 or 4 seconds and I add fortunately because pushing the Molicel P42A to 55A or 10A beyond their maximum is not at all safe, I had already written that with X75 it has certainly won the marketing of the numbers shot on the cover, I believe that those who like me bought it did it more for the 20k lumens for 20 minutes than for the indecent numbers of maximum emission and launch. For the launch I didn't have high expectations, on the other hand it is a flooder and almost all of these are so blinding up close that they do not allow you to see very far. Thanks for the fantastic photos of the drone which are like x-rays for a flashlight or clearly show the performance with strengths and weaknesses and it was a truly brilliant idea because the images speak for themselves much more than 1000 words.
The 45A rating for the Molicel P42A is only the max continuous discharge rating down to 2.5v, not the pulse rating. The X75 isn’t pulling 55A per cell continuous, so therefore isn’t a safety concern. The X75 steps down fairly quickly.
I don’t think that is definition of pulse discharge. Pulse discharge should be something shorter than 1 second or even shorter calculating in milliseconds.
