These are nice bright lights that originate from linear tube lights. I purchased a dozen strips, some were as pictured (with a P/N on the back of TTN1500-REV1) and some were slightly different (with a P/N on the back of TTN1013-REV3 ). The TTN1500 worked well, on my test bench using a GPS-3030D supply, they lit up at about 26V and full brightness was at 31V with a current draw of 180-205mA (varied between strips). Not sure how the other reviewer had 600mA going to these? TTN1013 had 3 solder pads with no markings and no matter how I hooked up power, they would not light, there are 45 LEDs on these strips. I could get individual LEDs to light with a diode checker. TTN1500 has 44 leds grouped in sets of 11. The temp of these lights is not warm, they are neutral, around 4500K.

Definitely NOT "Warm White"
Reviewer: A viewer

This strip is a "neutral" to "cool" white in color - definitely not "warm" white as the title indicates. I'd guess 4000K to 5000K. It has 4 parallel sets of 11 SMT LEDs in series, and no resistors that I could see. Would be easy to cut into series strips of 11 (or fewer) LEDs for smaller applications or lower voltages.
The strip barely starts lighting up at 1mA, and is pretty dang bright at 300mA. At 600mA it was blindingly bright and also starting to get hot. 2 stars because I expected it to be warm white (3000K to 3500K) which it certainly is not.
