Here’s what I would do since I have both. I would buy the FandyFire STL-V6 first. It’s right at about 48 to 50Kcd. Deal Xtreme is where I bought mine for $45 and change. Then I would buy the Small Sun ZY-T13 from Manafont for $24 shipped. If it were me, I would buy 2. You will like it that much. You can’t beat that light for the money in XM-L flashlights. The beam is perfect and I do mean perfect. I love my 2. I would guess this light to be around 40-42Kcd.
That other link for the SkyRay STL-V2 I know nothing about them.
The FandyFire STL-V6 is one bad thrower for less than $50. There’s none that will beat it that I know of for the money. It’s just a little shy in the throw department of the better quality throwers like the Olight SR51, Sunwayman T40CS, Olight M3X, and Crelant 7G5, all of which I do have.
This or that big assed halogen ilf has, or any of the plethora of 1M candle power huge reflector spot lights.
Their all basically a h4 bulb, 7+” reflector, 12v battery pack and a shoulder strap lol.
I’m thinking of fitting mine with a 14.8v li po pack, and before someone says it’ll blow the bulb, stick your multimeter on your cars battery terminals….
FWIW, earlier this morning I was comparing my T13 to the HD2010 with some white walling. My T13 has a hotspot 2/3 to 1/2 the size of my HD2010 and it's brighter, too! Still haven't had time to do full draw rests or lux and IS testing but will later this week.
