LED Flashlights – General Info 21700 Flashlights

@timbo114 & @BOOSTED or @Wurkkos, I'm curious about this as well!

@Wurkkos, when will the two new colors (Champagne & Metal Gray) be available on Amazon.us? TIA to all!

UPDATE/EDIT: Although I would still like to know how to get the TS21 from Amazon for under $30.00, I just noticed the following information was posted earlier today for those interested in the 2 new colors.

Flash deal of TS21 new color on wurkkos.com $29.99 on 1st.Oct

Anyone have a output graph? I wonder how many lumens it can hold starting at top of ramp.

51

The TS21 is a small, light weight, light. It gets hot quick and the output will decrease based on the max temperature setpoint in Anduril. That temperature setting is what will determine the output level. With factory settings, my light dimmed pretty quick. I set the temp to 60 and it gets too hot to hold before I notice any dimming.

52

So maybe 800 lumens?

lumaniac did this and it showed the top ramp holds around 80% for a substantial amount of time (24 minutes) when set to a max temp of 60%. 1lumen measured turn on at 1655 lumens at top ramp, so still holding around 1324 lumens after 24 minutes. Note this is highly cell dependent, in fet mode and with cooling.

This is the reason now why I’m going to buy it, for trail riding with air flow it appears to hold substantial light output.

If Wurkkos keeps this up, they will be outselling Convoy.

56

The code I had took $10 or so off the light and I had an Amazon credit of $15 I believe. Total shipped I paid like $25.

Hi. I have question about T21S. Is that 4000K SST20 is high cri variant or ordinary low cri?

58

I don’t recall seeing that listed either way, but since the IF25A probably uses the same LED and it’s 95cri, I’d guess this one’s the same.

59

High CRI. Supposed to be, anyway…

60

I ordered the champagne on Oct1 for $33 shipped including the battery. Only problem is they are all on vacation for a week starting EOB that Friday for National Day and now all orders are sitting unshipped for a week. Hopefully they get caught up on orders quickly. My last light I ordered took just 10 days to get. This one will be twice that at best. Hope I’m wrong. :stuck_out_tongue:

Wonderful review!
Thanks for sharing

The temp sensor is on the driver PCB, not the body of the light. If you just take a temperature reading of the outside of the light after using it, it will not be the same as the temperature of the driver PCB.

If you leave the light off and let it sit for a couple hours, the entire body of the light as well as the driver will eventually equalize to exactly the air temperature of the room. This way you can accurately set your temp sensor.

I don’t worry too much about absolute accuracy when I set mine; I just try to get it within a few degrees of ambient. If I notice it’s stepping down too slow or too fast, I then just tweak the step-down temperature down or up, respectively.

63

No worries, but ach!, I gotta get pix up. Having “issues” ULing…

64

Someone who’s hiding out as a lumberjack and talks to his dead father would appreciate your taste :wink:

65

it is high 95CRI

I need help deciding on 5000k or 4000k. Problem is I usually like 5000k for most my lights but everyone says the sst20 5000k is “puke green”. I run my lights mainly on high. Can I expect not to see it?

67

I have only 3 emitter FW3A with SST20 4000K. For now I think my favourite High Cri in 3535 format is LH351D. SST20 4000K are not green at low levels but maybe they will be very warm for you especially at low levels. Also I have IF25 with SST20 6500K and 3000K. 6500K are very greenish at low levels. I think I have also Skilhunt E2A with 4000K and 5000K sst20 but it lack to have very low moon output to compare them side by side.

Thanks
