It seems every BLF members prefers these drivers. If that is the case why dont manufacturers produce more lights that use these drivers.
It seem more are doing it today but still only about 10% of the lights have them.
Is it a cost issue, technical issue? Why not sell what people want/demand.
Yes, yes
Most people outside this community might not know what a buck/boost driver is. Even here many folks are OK with unregulated drivers, look at the quantities of the TS10 bought.
90% have them. If you pay 40$+
It’s not a cost thing. If we look at Convoy’s C8+ with SST40, same price for both linear and buck drivers. Only if the buck driver has also some disadvantages (can’t sustain a very low level? lower max brightness than the linear one?) makes sense to talk about different drivers’ technologies. Gaining in light duration should make everyone prefer the most efficient driver. And i don’t think burning excess battery power as heat should be accepted any more.
3 usd difference is the problem? I 'm talking when you buy a light at Convoy, price is the same, either you choose buck, either you choose fet.
I was talking about lights that came with those drivers, not lights where the driver can be swapped.
Also, only recently has Simon added multiple driver options to hia new web site.
Also, as far as I know jusr recently has FF gave Lume X1 as standard driver.
Isn’t this type of driver new to Emisar as well.
For a $15-25 flashlight ? Yes.
Especially because if you want good efficiency you need good quality coils and the proper ic and setup. Chinese companies(usually those who make sub 40€/$ lights) use lower quality components to save money. This is why you see so many lights with those powerfull emitters but horrible colour. Same with small components, even resistors and capacitors but the problem is with the ics which are harder to reproduce. So you go from using cheap domestic parts to having to use expensive foreign parts. Also the space requirement is more sometimes beacuse of the coil.
TLDR: Quality parts are expensive and cc drivers need those so its easier to slap a fet driver into something and pwm so horribly that i can literally hear it.
It’s been an extra cost option for a while.
I didn’t go for it with my D4SV2 as I wanted that instant burst of bright light. There was a comparison video done by somebody and there was a substantial difference with an otherwise same spec D4SV2 comparing turbo.
I absolute love what Simon does now with new web site. He offers many different LED and driver options. There is virtually no way to say he does not offer what you like, unless you want a different brand.
See here, scroll down to the beam shots Emisar D4SV2 Review – Three Versions Compared! – Grizzly's Reviews They’re labelled “W2 FET Driver | W2 Boost Driver”. You can slide the divider across to see the difference- there’s quite a bit of difference.
