Fireflies ROT66 Flashlight

Lexel designed the battery warning function.

Yeah it’s a great touch. I haven’t seen a low battery indicator quite a nice as this one.

You’re welcome, but I didn’t do that. :stuck_out_tongue:

Lexel made the aux LED board do its voltage indicator thing.

I have waited for two months for ROT66 and it will not happen, because even the statuses do not change. Firefiles, a few days ago, promised to send again and … silence, no response. Bad start. I guess I will have to write to paypal. :frowning:

They’re probably taken by the E-07 launch.

My rot66 arrived this week but defective, unusable. Probably some bad contact inside the head but I bought it glued. I wrote to Jack, let’s see how after-sales works for me :frowning:

if you don’t get a response in a day or two try a PM on here instead. I think it works better than the contact option on his website; I don’t think that works. I wish I could help; he needs a daily presence on here to help coordinate. He does resolve every issue to each person’s satisfaction but sometimes it takes a minute.

My complaints have turned out well. I got new. Waiting for it was not pleasant. Faulty lamps are a great deal of how much they sold. In addition, it is always possible for a newly dispatched flashlight to be lost, it will have to pay VAT and customs fees (in the EU). Nevertheless, I believe FF for now and buy E07.

I feel your frustration because I’ve been there with my Enogear AA experience, which took months but ended up a satisfactory experience. I bought 4 ROT66 from him at different times. The first ROT66 I bought on day 1 it was announced, before the group buy started. That one took I think about 3 months. It was shipped out earliest and I had tracking number but I guess it might have been stuck at customs. The other ones came between 2weeks to a month. I know it’s hard to wait, but have a little bit more patience. You can PM Jack here. He takes weeks to respond to emails but he responds to PMs in a day or two.

Yesterday I placed an order on: http://www.ff-light.com

I did not get confirmation email which is very strange. Also no registration email.

Till now they did not send me FL. Do you know how quickly they normaly send FL?

Thank you

Kind regards

When I see FL I can only think of Florida, which isn’t in Romania, so it must mean flashlight unless you moved. Out of all the words to abbreviate :stuck_out_tongue:

I didn’t receive confirmation when I ordered mine until several days after placing the order. It is shipped from China by a low cost method, so expect to take several weeks to possible even a month.

My ROT66 continues to be weird. I was using it over the weekend and so I left batteries in it. Sure enough last night while sitting untouched on a shelf it turned itself on again. Now I can’t get it to work at all. When I first put batteries in it turns on and ramps up to max, stays there for a few seconds, then blinks and turns off. It is unresponsive to any button input, including trying a four-click to lock/unlock.

Anybody know what’s going on? Should I try to return or warranty the light? I like the tint of the Nichias but I have a hard time ever trusting this light to be useful when I need it.

Mine flashes all by itself now, coming on briefly or blinking, main and auxiliary LEDs. The batteries were at 4v when this happened. Jacky is sending out a new board

Boy the e-switch sure sounds like the culprit . S%$#@ happens, and sounds like it happened right in that switch. Might be some cleaning agent or flux, or something gunked up, or maybe the wiring/PCB/etc. I think the ramping up to shutting down is by design. Sounds like something I did (and/or TK) to handle the case of a stuck switch - think I made my timeout 20 seconds, where it would go into lock-out mode if that ever occurred. This is to prevent the light from being on if the switch was jammed in the ON position, like in a bag or pocket.

This sounds like a power flicker/outage, like you see sometimes when tightening up the tailcap where intermittent power contact is occurring.

Thanks for your input. I just ran a test again and I noticed that the switch always has 2 lights on, never 4. This would seem to confirm your theory that the switch is stuck on.

I haven't looked carefully at the ROT66 but so many of these lights have very tight tolerances on the switch wiring pads. So it may look good from a visual inspection, may even work fine at the factory, then after shipping, ever so slight shifting may cause a short. Or again, some contaminating agent after time gets more conductive.. So many things can happen.

There's been issues with e-switches, but just by design really, really prefer them. Over time, mech switches are prone to more likely failures, plus a lot of amps going thru thin metal and small contact points internally in the switch is not a good thing - e-switches don't have high power. The only somewhat superior mech switch is FET based, so high amps is not going through the actual switch, but these are more pricey, probably bigger, and I just don't see these offered as replacements anywhere.

Random Dan, that definitely sounds like a problem with the e-switch. It sounds like it’s shorted to make it think it’s always being pressed. It could probably be opened up and fixed, if it’s not glued, but that’ll definitely require some soldering.

Thanks for the troubleshooting help Tom and Toykeeper.

Since moving I no longer have access to tools, so I will probably try to send the light back to Fireflies once I return from holiday travels.

Is there a way to turn off the blue aux LEDs? It doesn’t look like it’s covered in the basic UI diagram but I understand there are lots of ‘varsity’ features buried in there. Thanks!
