[Review] Pretty good low budget 1x18650 lantern

Vegas LED Fan:

Just looking at the link to the product shows up some questionable data. The light uses 24 white SMD 2835 LEDs and claims to use 20W. The typical draw for these LEDs is 0.24W per LED but that is for a 60 LED per meter strip using 12V. There is some loss in this strip by the small resistor that accompanies each three LEDs in the strip so it works on 12V DC. Even at 0.2W per LED the power consumption for 24 LEDs would be under 6W, nowhere near 20W. That’s actually pretty good as if this light actually did draw 20W, the run time would be very short between charges.

How bright is “bright”? Output for a typical 2835 LED is 1290 lumens for a 60 LED cool white 12V strip and 1200 lumens for warm white. 1290/60 = 21.5 lumens per LED Times 24 = 519 lumens. That’s about half what my budget CREE XML-T6 flashlight puts out on high setting. To answer siata94’s question, the Zanflare Z1 flashlight uses one CREE XML-L2 LED. The Zanfare listing shows the output to be 1240 lumens on high. This matches exactly the data in the CREE Data Sheet for the L2 LED.

It is probably a perfectly good light for the price. Just wish the seller would be a little more accurate with the specs.

I did a review of a very similar light I got from Amazon a while back. I think it’s in the 300-400ish? is Lumen range.

RC linked to this in his OP.
It’s quite sturdy. Good thick plastic.
On mine, only a flat top, or a very short unprotected button top will fit. Batt tube is quite short.
And there is no low voltage cut off on my example, so left unattended it’s a battery drainer.
All the Best,
Jeff

PS, accurate descriptions of real values? On Amazon? “Nary a chance” says I.
You are lucky to get a review that is actually the same product that is for sale.
