ReviewTheLight: Thrunite T30S V2 (860 Lumen, Dual Rear Switch)
my reviews on facebook!
Don't forget to click "Like" after the page loads! to my YouTube channel! Thrunite... Thanks to Thrunite for providing the T30S V2 for review. I’ll be reviewing the T30S V2 in two sections: first, I’ll discuss the light objectively (the facts about the light itself), then I’ll discuss the light subjectively (my impressions about the light's performance when used for specific applications). If you have any other specific applications you'd like the light tested for, let me know and I'll see what I can do. Video Review Below is a video review of the T30S V2. Due to my old image hosting site closing down, I've got new restrictions on image uploads and have replaced the "Construction" section of my reviews with a more detailed video review.
This video is available in 1080p HD, but defaults to a lower quality. To select the playback quality click the settings button (looks like a gear) after you've started the video. Objective Manufacturer's Specifications Price: 50 USD Product Manual Dimensions Plus, here's a few shots with some good detail. User Interface Coming soon... Action Shots You can click on any of these shots to see them full size. Light in Hand MugShot BeamSlice White Wall ISO 100, f/3.5, 1/20" Indoor Shots ISO 100, f/3.5, 1" Outdoor Shots ISO 100, f/3.5, 2.5" Performance Submersion: I submersed the T30S V2 under a foot of water for about an hour, clicking both switches several times. I found no evidence of water entering or damaging the light. Heat: PWM: Drop: I dropped the T30S V2 from about a meter onto various surfaces (including grass, carpet, dirt, and hard wood), and found no cosmetic or functional damage. Reverse Polarity Protection: Over-Discharge Protection: Spectral Analysis All light that we see as white is actually made up of several different colors put together. The relative intensities of the different colors in the mix are what determine the tint of the white we see. For example, cool white LED's have a lot of blue, and warm white LED's have more red or yellow. This measurement was done on a home made spectrometer. The plot below the picture is corrected for the spectral sensitivity of the human eye. Note: the peak in the 900nm region doesn't really exist, it's a piece of the second-order spectrum that's showing up here because of the high intensity of the light source. Output and Runtime ANSI FL-1 runtime ratings are the time it takes for a light to fall to 10% of it's original output (counting from 30 seconds after turning the light on). The vertical axis of the graphs below represents a relative brightness measurement using a home made light box. The horizontal axis is time in hours:minutes:seconds. Runtimes are stated in hours:minutes:seconds. These graphs may be truncated to show detail. Mode Comparison High Medium Throwing Distance ANSI FL-1 standard for stating a light's throwing distance is the distance at which the peak beam intensity (usually at the center of the beam) is 0.25 lux. I calculate throwing distance and candela (lux at 1 meter) by measuring peak beam intensity at five different distances and using the formula lux*distance^2=constant. Note: A calibration factor of ~6.88% has been added into my throw measurements starting on 9.11.14. To compare the throw of a light I reviewed previous to that date, multiply the candela value by 1.0688 to get the corrected value. Subjective Review Quick break down: + - Coming soon... Long Term Impressions I'll fill this part in after carrying the light for a while. If nothing get's added here, either I find nothing else worth noting about the light, or I end up not using it often. |
