I haven’t bought this particular boost driver as yet but, the 6009xl drives an 1512 LED ok with a 2S pack and good with a 3S LiIon pack (added heatsink hardly warms up driving the LED at 1A,) . The little driver below should easily fit in the body of this bulb

Amazon has Ganzo G735 assorted colors for $11.95 sold by ACE KNIFE. Free 2-day ship for Prime members.
This is a great deal on one of Ganzo’s more recent models.
The next closest price I could find was gearbest for $17.01
Mine just arrived yesterday (G735-YB Yellow & Black), and best of all, it arrived in 2 days!
I’m used to waiting for the slow boat from China, but this is stocked somewhere in the USA.

Flash deal, act quick.
RAVPower 26800mAh powerbank $35
https://www.amazon.com/Portable-RAVPower-Technology-Smartphones-More-Black/dp/B012NIQG5E
Actually $32.99 with code 26800RAV
bummer that it doesn’t come w/ cable to jump start a vehicle, doesn’t look like it has the
correct connector for one neither.
For a powerbank to start a vehicle the battery must be high drain LiPo in 4S, the ravpower one uses 18650s in 1S configuration.
Superway 10,400mAh lantern / powerbank combo
Got one last week and it is great, measured 32Wh output at 5V 2A which means the 10,400mAh rating is REAL. About 400 lumens output and extreme runtimes in medium and low. Well built although glued all around so no modding possible. CW tint 5,700K with nice spread, about the side of a meteor.
I have a quick review coming soon when the runtime tests are done but I’m going to give you my word for $22 this is a steal, you won’t regret it.
Wowser, that's some serious run time. Looking forward to your review. How do you get it for $22?
delete.
At the time of my post there was a flash deal going on and it was $22.40, right now the price has gone back up but you can find the exact same lantern under other brands for about $28, or pay $36 for this superway one and get a smaller 4,000mah version free.
Runtime was Over 20 hours on high and 70hours on medium, not fully flat but a steady drop to about 50% power then LVP kicks in. Review should be up this weekend.

I was looking for some short KP protected 26650 cells for a friend and came across this deal on protected KP NCR18650B.
Next best US price I could find was ~$41 for different brand protected NCRB’s with slower shipping.
$36 with 2-day prime seems pretty good.

Buying lithium ion batteries through Amazon from a third party seller calling itself a Grocery already seems strange enough, but one named Bang Bang ???
I purchased those same cells linked from that seller. I made a similar comment at the time to wife, odd name indeed… Bang Bang Grocery, hmm… not sure what they’re aiming for here. Nearly two months later and no issues with the batteries far as I can tell! Try CamelCamelCamel and paste the AMZ link there to check the price history of an item, see if it’s really at an all time low and if there’s a pattern to price fluctuations
It’s fulfilled through Amazon. You can pick the other Supplier if it makes you feel better. 
Either way, they can be returned for free if you notice anything even remotely out of place with them.
