I expect a S21A SST40 6500K and compare a 5000K S2+ SST40
My choice to have fewer battery types would be:
A M2B XHP70.3HI R70 5000K or 6500K doubted R70 or R9050 but Simon says that the R70 in 5000K will illuminate more than 5000K.
And a S2B XHP50.3HI 5000K or 6500K (wanted a S11 XHP70.3HI)
S21B is because he wanted a more tactical tube design, I think they’re easier to take and if it’s not comfortable, I know I’ll leave her home and I won’t take her.
I’ll leave the one I like from the beginning S11 XHP70.3HI 6500K because it uses battery 26650, I don’t know if I’ve done wrong because it’s a few millimeters with the S21B
In the S11, it enters almost all the sizes of Leds and Driver, it would be easy to change and test.
I guess S21B with the XHP50.3HI will consume less and last longer.
What do you think?
The 5000K or 65000K is because I will have both to see the color with my own eyes and decide, the S2+ SST40 5000K has an amazing color, I love, it looks sunlight!
Do you know if Simon makes us the discount only on the first purchase or all the next shopping?
I asked him and I answered how to do it.
As I have doubts, it was to buy one and then one or two later.
But if the discount is with the first purchase, I make a full order.
I think the 70.3 is a bit more efficient than the 50.3. But I am not sure of the differences in driver used. But I think it would be close to even. Not there is enough of a difference that you would notice this much in real world use.
I don’t think it is limited to the first purchase. I have never used the discount because I have not been clear on how to do it… and I think it is not huge anyway. Hopefully someone else that is more familiar with the process can comment.
I think you have a good plan. Get some lights and play with them. Figure out what you like. Next order will be easier.
I think the previous post is a “much more light” great! option. I put an XH-P50 in a S21A, with a sanded TIR, narrow pattern. Of course, I used a 6V, 2*cell required driver. It puts out an awesome amount of light and actually, quite far, too. With a boost driver, 1 cell is so convenient.
I have decided on the M21B XHP70.3HI R70 5000K plus battery.
Because if I wait to look for more models I will never buy and I want to have one now!
I liked the tone of an S2+ SST40 5000K, that’s why I also chose 5000K, I don’t know if I’m going to lose a lot of brightness compared to the 6000K model
What is your opinion?
Things look more natural at 5000K
Or better another model?
I am looking for something easy to carry, it will always be in the hand or in a convoy holster for a belt but I like the tube type S2+ S21A s21B S11 but I think that the M21B having fins will dissipate more heat, if not then I choose the S11 that uses copper or brass pill maybe it sisps the heat better but it doesn’t have fins and if the tube design, what a mess!!!
I think you will be happy with it. Good lights. I have 4 of them.
You won’t notice any difference visually… I mean even if you had the two lights right next to each other. If you had the equipment you could measure a few percent difference. In real world use any difference is negligible.
First, the S11 doesn’t use a pill. Driver and MCPCB are mounted to a shelf in the head. Again the differences in heat dissipation are minimal. Maybe there would be a difference of a few seconds in stepdown using 100%. But likely not even that. Using anything less than 100%, you might not even be able to measure any differences .
I think that most of the time chasing the best numbers is counterproductive. To me, other factors like form factor, UI, and runtime at reasonable levels all are far more important. In other words, don’t let the pursuit of better numbers get in the way of finding a good light for you use case. It is not anything like having your timing device in your rally car be off by a few tenths of a second… or your GPS being off by 30 meters.
Again. I apologize. But in any case, I think that the pill design is not as efficient as a shelf for conducting heat away from the LED and driver. So the S21B is likely better at that. Though I have not had any problems with thermal regulation or damage to the light using the S11 with XHP 70.2 LED. (I used it quite a bit when I first got it) So it is not an issue that I would worry about if thinking about buying one. Though, thinking about it now, being a bit OCD, I may go in and add some thermal paste to those threads,
Seeing the design you can be quite right, the pill is threaded without any thermal paste towards the head or thread, that is, the heat is dissipated for the most part in the pill.
The designs without a pill are directly linked to the entire body of the flashlight. I suppose it will be a greater dissipation plus a base, although you will notice it more in the hand.
I have not seen them disassembled, it is only theory, the pill design will dissipate better if it is copper and as large as possible, in addition to being solid and not hollow, I see that most pills are hollow with a smaller base and it is not copper, it looks like brass .
I already decided on the M21B XHP70.3HI 5000L R70 I wanted the highest brightness, I think it would be the 6500K but as you say the loss in 5000K will not be much if it is R70 I suppose.
