| Sep 2, 2015 at 15:32 | comment | added | feetwet | Wow: That LED has amazing output! Kind of funny how it's basically a giant heat sink with a tiny panel on one side and battery on the other. Asking the community for data seems like a great idea to me. I asked on meta why not meta.photo.stackexchange.com/q/4846/27832 and I expect we'll be reminded shortly ;) | |
| Sep 2, 2015 at 15:20 | comment | added | Harry Sanderson | Perhaps you could obtain the data by asking the community to perform various tests on different flashes and then collate the results? | |
| Sep 2, 2015 at 15:18 | comment | added | Harry Sanderson | Have a look at this YouTube video: youtu.be/c--5c3Egv4E it shows a DIY flash light using a high powered LED. It's probably a little large but it still gives you a good idea. | |
| Sep 2, 2015 at 15:16 | comment | added | feetwet | Haven't tried the Li-ion Neewers. That's part of why I'd like to see data on this question: Of course it's great if we're just popping a few flashes and heat buildup isn't a consideration. But I'd like to be able to reference the heat/cycle-rate/light-output for different applications. And then one could also bring the LED panels into the question in an intelligent fashion. | |
| Sep 2, 2015 at 15:15 | comment | added | Harry Sanderson | I would say flash is still more powerful however I bought some 5630 LEDs and they are incredibly bright to the point where they could be comparable to a speedlite. LEDs are interesting because the technology is constantly developing and becoming even more powerful! | |
| Sep 2, 2015 at 15:11 | comment | added | feetwet | BTW, since you're the second person to recommend LED continuous lighting: Are portable continuous LED panels really capable of approaching the power of a speedlight? Last time that question was asked the answer seemed to be no: photo.stackexchange.com/q/34225/27832 | |
| Sep 2, 2015 at 15:10 | comment | added | Harry Sanderson | Have you tried the new Neewer TT860? It uses a new Lithium Ion battery which means it recycles from full power in about a second. | |
| Sep 2, 2015 at 15:04 | comment | added | feetwet | This is with a couple of $60 Neewer NW TT660 II flashes, backed up by a relatively weak Sony F43. (I typically set key and fill with the Neewers, and I have the Sony as background/hair light.) | |
| Sep 2, 2015 at 14:54 | comment | added | Harry Sanderson | Interesting what flashes do you use? :) | |
| Sep 2, 2015 at 0:12 | comment | added | feetwet | Thanks, some good points here. NB: I wasn't guessing, I was observing that my flashes at 1/8 power running on internal Gen2 Eneloop AAs do keep up with 12fps shooting. | |
