Fireflies E07 preview

Drop-shipping 101. He should just have Fireflies ship it for him once he gets the order.

did I just make a funny

Neal just acts a middlehand having his own store, so i guess whne he is out of lights he must wait until FF sends him a new batch of lights to him ? i guess they do business different in china.

I think theyre both slow lol

Well luckily I ordered both before the Chinese New Year holiday. That appears to have thrown a monkey wrench into many customers orders.

I’m still waiting on my order too. I ordered Dec 21st from Fireflies and received a shipping notice around Dec 25th. The tracking number still just says “International item has left originating country and is en route to Canada” so who knows when it’ll actually get here.

wow thats crazy… u should contact them, it would have arrived by now dont u think ?

Yeah, I emailed a couple days ago. No reply yet.

I put an order in on New Year’s Day and another on Jan 2nd. Standard shipping. Both arrived in Canada a month ago.

Yeah I kinda figure if I don’t get at least a reply within the next week or so I’ll have to file a paypal dispute.

Anyone with a calibrated tube/sphere have a nichia e07? What is the 1x7135 lumens? The mode that comes on after you redo the tail cap by default.

Ok, finished my E07 led swap today. Nichia’s in the clear ano light now. This install
went much smoother than my first. Both have layer of thermal paste now. I noticed there has to be some variance in the drivers because the nichia E07 moonlight mode is now the dimmest. I thought it was the nichia/XPL thing before now. I may try some beam shot/tint comparisons later.

I suspect you changed the floor setting (by mistake) on the brighter one. Go through the steps to set it back to 1, but it may or may not flicker a bit on that low of setting

Isn’t the brightness difference due to the XPL being much more efficient in lumens/watt compared to the nichia? ie. for the same milliamps and volts the XPL will be brighter.

He swapped the LEDs and the issue did not go with them. So presumably it’s a hardware (7135) variation or firmware (floor setting) difference.

Lol, I did. No flicker, but that’s the floor on both. One click on both setting up floor.

My previous post will show the XPL moonlight lower than the nichia before the swap. I think it’s got to be something with the driver

It’s those small variances in componentry that cause it to be difficult to pre-set moon… they just aren’t all the same.

That's why I made moon mode level configurable - I got lights with a "glow" for moon light PWM level 3, some work decently, others don't light up at all on PWM level 3. Also some work at level 2, and I think at level 1, some don't.

I managed to reduce the hardware sensitivity of moon level, but didn’t eliminate the issue entirely. The method for doing this is to underclock the MCU at the lowest few levels, which makes each pulse longer but farther apart. The overall brightness is similar, but it’s less volatile, less variable from one chip to the next.

Comparing the two methods…

Adjustable moon at full speed:

  • + Moon level can be lower.
  • + Moon level can be somewhat more consistent from one light to the next, if each one is calibrated individually.
  • + Virtually impossible to detect any PWM.
  • - Moon may be fine on a full battery, but may not illuminate at all on a low battery.
  • - Generally requires calibration for each individual light.
  • - Uses about 5 to 6 mA of power, even at the lowest moon level.

Dynamic underclocking:

  • + Less sensitive to subtle hardware changes, so moon level is more consistent from one light to the next.
  • + Less sensitive to battery voltage, so moon level is more consistent as the battery gets low.
  • + Uses about 1.2 to 2.2 mA of power, so moon runtime is typically about 3X longer. The next few low modes also have increased runtime.
  • - Not adjustable for each individual light.
  • - Moon level may be higher than desired.
  • - PWM might be visible for a few people… though it’s still invisible to most.

Six of one, half a dozen of another. Different people choose different tradeoffs. Perhaps in the future we’ll use MCUs with more pins and we can have a dedicated power channel for moon… like how the lighted button works. Or the button channel could be used for moon instead. This would provide even higher efficiency, with no PWM.

Still waiting for word on copper and/or titanium version!
