Fireflies ROT66 Flashlight

The SST-20 throws farther than the XP-L HI

I was about to mention sst20 have good throw… this light is a little beast…

I’m not sure if it throws farther in the ROT66, or just in the GT-Mini. Regardless, the ROT66 isn’t a throwy light no matter which emitters it uses.

As a side note, looking at Vinh’s throw numbers, everything looks about 30% to 40% higher than it should be. I’d suggest multiplying those by about 0.75 to get more accurate numbers.

Vinh’s numbers are a bit higher than measured with Maukka’s calibration but I think 0.75 is a bit much. I think I measured about 1,200 on my XP-L HI 4000k version and others measure 1,2xx lumens with the XP-L 5000k or 6500k version. Vinh measured 1,300 lumens on the 6,500k version.

Edit: Oh sorry you mean throw numbers not lumen numbers.

Yeah. The GT-Mini with XP-L HI gets about 120 to 130 kcd, not 170 kcd. And I’ve noticed similar differences on other lights.

Anyway, the ROT66 seems to work pretty well with SST20 emitters. I still prefer 219B though.

Do you think it is cheaper to buy it from illumn ?

SST-20 is like XPG2 sized die, so dedoming it should be pretty equivalent to dedomed XPG2— probably a little less throw. I can see SST-20 dedomed out-throwing the XPL HI.

Once I get my SST-20 4000k with 804 filter over it from Vinh, I will vigorously compare it to the 219B version. The LH351D 4000k + 804 has a nice tint, but it’s just too floody for my tastes. Others will probably like the sheer output and wall of light kind of hotspot it produces.

Rot66 Sst20 CW

Samsung 30q. 6300 lumen.

After cleaning the contact and carrier…

Samsung 30q… 6800 lumen.
Sony vtc5d. 7000 lumen

I cleaned the battery carrier with the alcohol when I tested it with the Sony.

I use liionwholesale. Great prices.

Recently I bought two big orders from 18650batterystore.com. They have good sale items all the time.

@raven+SKV89, that’s not the problem klrman is facing.

It’s two things:

1. The US dollar is stronger than the Canadian dollar.

2. But most importantly, lithium ion shipping is stupidly expensive in Canada.

I agree. I hope fireflies find a way to send you those 3 samsung 30q.

Yeah that is going to be really hard, especially to Canada.

Over here in Singapore, we’d use “sensitive air” option from 3rd party forwarders to ship Li-ion from Taobao. First kilo is SGD 11, subsequent 0.5kg SGD 4. Of course to make the most out of the consolidated shipment, you can send other orders as well, eg other flashlights from other sellers, and then consolidate the shipment before forwarding it to the destination country.

Don’t even think of smuggling in by trying to camoflauge the order (customer raises an order and pays for innoculous item A, ask seller to change the price, seller ships 12 x 18650s :slight_smile: ) or mis-declaring it on the performa invoice. Both the goods warehouse and air freight carriers scan their goods very tightly nowadays. Esp after recent few years some buggers used this route to smuggle drugs.

Normal goods (eg underwear, clothes, toys, kites, faucets) current prices are SGD 6 for the first kg, subsequent 0.5kg 2.

For the super sensitive goods, gotta go by “sensitive sea”, eg neodymium magnets. Cheaper though, but you gotta wait for 2 weeks. And some things like processed foods are limited to 5kg, but that’s due to local regulations and limits, not the carriers or overseas (china) customs.

I believe Shunfeng Express can do it too, but the cost is gonna be eye-popping. Still, probably a tad lower than DHL. :smiley:

Buy a new light + 6 batts, and ask for a discount? :smiley:

If I were a FF boss, I will give a customer 50% off the light and free 3 18650.

Nah. Just offer to pay shipping for 3x18650s for the customer. That is probably going to be expensive for them to ship directly, so that is a good punishment already.

Had to try it out so I broke a four pack of 30Qs into three but for some reason I can't get the battery cage with the cells inserted back into the battery tube? Is there some kind of trick to this? No matter how I try, the batteries slightly protrude width wise and there is no play to slide the cage back into the tube.

I just tried my 30Qs from Banggood and Illumn. There is no way this is going in the rot66 battery tube, it's that tight. I tried to force it a little and now the top side of on of the 30Qs has cut through the wrapping. This would probably explain why they were shipped without batteries on mine.

It was upside down inside mine when it arrived.

Hmm….this “issue” has also been reported in one of the Taobao user reviews i have read. Anyone?

ROT66初版差強人意,以CP值來說算是不錯的。*電池倉裝上電池和筒身太密合* ,按鍵燈斜了150度,九顆燈珠有一顆亮度明顯暗於其他顆….期待下一版會更好。

>>The battery compartment when loaded with batteries is too tight with the flashlight tube barrel

The way I see it, someone at FF sent this light to me knowing the battery tube tolerance is faulty. Too much of a coincidence that they forget the batteries and that the batteries won't even fit. I can't figure out if it is the cage or the actual tube that is the problem, but I'm thinking maybe the cage is not allowing the batteries to come close enough together to fit in the tube.
