![]() Though I think the looping design might be slightly more fiddly than some straps I’ve used. This light is much more at home on the handlebars of my bike. I definitely noticed the weight up there and needed to cinch my helmet down more than usual to keep it from shifting. However in testing this, though it does mount well and hold the light securely, the light is a bit on the heavy side for head mounted use. The GoPro mount seemed the like the perfect combination for use with my Bell Super 2r breakaway GoPro mount. My hope had been to use this as a helmet-mounted light. ![]() For mountain biking, except if you are riding to the trail, these are pretty pointless. These side lights are supposed to make you more visible when riding in traffic and on the road. The second button controls the secondary side visibility lights. ![]() The first one is the main power button that also controls the mode of the 3 main LED array. The body of the light is fully metal and is FL-1 certified on ANSI-NEMA testing scale for impact resistance. Which means it is tested to be fully waterproof in 1 meter of water for 30 minutes. It features a waterproof design certified to a IP67 Rating. The light includes two different mounts, a rubber strap for attaching to handlebars and a gopro mount. The port is easy to expose and get plugged in. The USB charging port is on the bottom of the light and features a usb mini charging port with a gasketed cover. The Taz 1200 is a self-contained, usb rechargeable light. They also stand behind them with a 2 year warranty. First, Light & Motion is a US based company that actually assembles their lights in the US. Light & Motion has a few unique selling points that attracted me to testing out this light. ![]() This winter I tested out the Light & Motion Taz 1200. Reading lights tend to be marked 5000-6500K these appear much bluer and perceived as brighter.Dedicated winter riding usually means night riding. For whiter light – more akin to daylight – good for kitchens and workspaces, bulbs labelled between 3500-4100K would be best. Incandescent bulbs are around 2700-3000K and produce a yellower warm/soft light, great for creating a relaxed ambiance. Light colour is measured using a temperature scale called Kelvin (K). Choosing the colour temperature of bulbsĬhoosing the right colour is dependent on the atmosphere you’re trying to create within your room, or what the space you are lighting is used for. Bulbs that are nearer to daylight (bluer or cooler in colour) sometimes appear brighter than yellower coloured lights. The colour of light can also affect how bright a light appears, even if the lumens are the same. Incandescent Bulb Wattageĭata sources: American Association of Physics Teachers 1996 and Energy Star 2016 What else can affect brightness perception? An equivalent compact fluorescents (CFL) bulb in light output (lumens) should consume only around 7 watts and LEDs approximately 6 watts. Wattage to Brightness ComparisonĪ 40 watt incandescent filament bulb produces roughly 460 lumens. Some of the most energy to light efficient LED bulbs are now reaching over 120 lumens in Energy Star tests. On average, an incandescent bulb produces around 14 lumens per watt, compared to 63 lumens for energy saving compact fluorescents (CFL) and 74 for LED bulbs. Most of us have a preconception of how bright a 100-watt incandescent bulb is even though this can vary tremendously between soft white and clear glass bulbs. Lumens is an accurate way of measuring the light output of bulbs – brightness is what we perceive, luminance is what we measure. They come in varying technologies, such as Compact Fluorescent (CFL), Halogen and LED and they last much longer – up to 25 years for LEDs!ĭefining the brightness, or light output of bulbs is changing from wattage equivalents to lumens. Nowadays, energy saving bulbs produce far more light, less heat, whilst consuming less energy (Watts). In recent years choosing light bulbs has become far more confusing – you knew roughly what you were getting with a 40, 60 or 100 wattage filament bulb. Household cost based on 12 bulbs.Įlectricity costs are calculated using the UK: Energy Price Guarantee (Oct 2022) electricity rate of £0.34 per kWh (incl. *lumens conversion based on averages of Energy Star LED/CFL testing data 2016
