Convoy S2+

Just seen this http://www.gearbest.com/led-flashlights/pp_44147.html which looks like a bargain.

However am I better off spending the extra for XM-L HI with biscotti firmware?

What do you guys reckon?

Thanks

Yeah, that’s a very good deal. I was going to order one of those, but decided to order a BLF A6 instead. Seems like the A6 is a very similar light, but the user-interface is way better. Almost twice the price, but I think I’ll use the A6 more than twice as much as an S2+.

As a 3-mode light, the S2+ isn’t bad. But, the annoying blink when in low mode (to program the 3 or 5 mode selection), seems like it would really bug me. I know it’s a minor complaint, but really? They couldn’t come up with a better way?

I'll second the BLF A6.

It's my EDC, and I like it a lot more than my Convoy S2+.

Thanks

Edit. A6 looks awesome.

Ok So have found the A6 on Banggood.

There seem to be two options. They look the same but the second one comes with a 30Q battery. Strangely this one id £5 cheaper???

Yeah, I found that odd too. I think it’s just different listings, and they don’t always put them all on special at the same time. I ordered the one that comes with the battery. It’s a good battery, so why not?

Ok I am on the verge of ordering.

However I’ve searched the forum and can’t find an answer to this.

The specs from Cree seem to indicate that the cool 1A LED produces more lumens for the same current than the warmer tints.
Does this mean the 1A version is brighter?

Yes, it does.

As a general rule of thumb, cooler tints are more efficient and therefore brighter than warmer tints, all other factors being equal. This is an effect of LED physics and applies to all manufacturers.

The reason warmer tints still sell is that many people prefer them and are willing to lose a few lumens in exchange for light that looks nicer to them.

In my opinion the biscotti driver is worth it, no configuration blink in low mode, and many more mode groups to choose from, moonlight mode, which is absent in the 3/5 driver

That’s a good one to go for.

I have a couple of those myself. They offer a nice combination of practical mode levels for day-to-day use and silly-bright ones to play with Smile

grumpazoid, Yes, the cooler 1A tints are brighter, but they wash out the contrast. To my eye, they make everything look two dimensional, like a cardboard cutout. The warmer tints, and my favorite is probably 5000K, which is neutral white, make things look more life-like. I just built some lights with a 3D tint. I really like it! There have been some very good explanations on this forum (SoCalTiger) about how light interacts with the eye. Polls taken here put 5000K at the top of the list. It’s not just a preference, it’s choosing what helps you see better. That’s what this is all about, isn’t it? Ollie

Biscotti is miles better than old UI and well worth spending a few extra pennies on. Don’t forget that you can get Biscotti in any S2+ on request at Convoy’s AliExpress store.

Why don’t they make it standard?

The blf A6 with 30q is on flash deal at Banggood, which makes it very interesting, i was thinking of buying it as well, but almost holiday so bad timing for me.

I have enough S2+ es now. Especially when the clear (from GB finally) arrives. (Still waiting)
Generally, shipping of Banggood is way better then GB.

(A bit off-topic, but…) It’s also about what you’re illuminating. A cool-white LED is brighter than a warm-white LED, but if you shine that light on a red towel you’ll notice that the warm-white light shows up much brighter. That’s because the warm-white light has more spectrum in red, even though overall it’s dimmer.

If you illuminate white-paper, the cool white LED will be brighter. That’s how it’s measured. But that’s not how the natural world is structured. If you’re in a mature forest, there will be a lot of brown in tree trunks and leaf litter. Brown (which is really a dim orange), is better illuminated by warm tints. So your warm-white LED light may actually look brighter than a cool-white LED light.

On green grass, the cool-white will look brighter. Cool white is optimized for blues and greens. Warm white is optimized for reds, orange, and yellows.

Ignoring brightness, warm-white LEDs usually have higher color rendition than cool-white. Cool-white LEDs are generally around 65 CRI, while neutral is around 75 CRI. Of course, you can get premium LEDs that give much higher CRI, such as a Nichia 219 LED (my favorite). But you pay a price for higher CRI, with usually much less brightness.

Yes couldn’t believe you get a battery included for much cheaper than the A6 on its own. Lucky timing for me. Cool

Update: Tested my new light out last weekend on a camping trip. Very pleased with it. Good quality and a lot of light for its size.

You can’t go wrong with a Convoy S2+
T6-4C is a nice tint as well and the blue one has a nice stainless switch!

The only thing I don’t like about that version (firmware) of the Convoy S2+, is the limited mode selections (and the blink on low). But, it’s cheap, so if you’re okay with the modes, then it’s a great buy. There’s versions with updated firmware, but they’re more expensive. Also the BLF A6, but it it more expensive too.

At that price, even if you decide you don’t like it, you’re not out much.

the only thing i hate about S2+ is the blink on low to change group with standard firmware BLF A6 is superior, get S2+ with bisscotti or flash it yourself.

I wish the medium mode was 25%, rather than 40%. That would give it a good long run time with decent output. And, as a 3-mode light, that would be better spacing.

The better approach is to just get the one with bisscotti. I presume they’re all going to be that way, once the older model sells out.
