Optiled Array LED AR111 11W 2800K 12V G53 20° niet dimbaar
| Beam angle | 20° |
?
The wider the light beam, the larger the illuminated surface. Brightness decreases as the beam widens, since the light is divided over a larger area. For creating high contrasts it is therefore recommended to apply smaller light beams. However, contrasts that are too high can be distracting and can cause adjustment problems for the eye, which can be tiring. On the other hand, too little contrast creates a dull and flat impression. |

| Colour code | 828 |
?
Light colour is often represented with a 3 digit number. The first digit indicates the CRI (Colour Rendering Index) or CRI Ra value: 5 = 50-59 6 = 60-69 7 = 70-79 8 = 80-89 9 = 90-99 The last 2 digits are for colour temperature. The higher the colour temperature, the cooler the impression of light. Warm white creates a cosy, welcoming atmosphere. Neutral cool-white creates a more businesslike atmosphere. Low lighting levels in interior must be obtained with warm-white light. If a very high level of light is needed, this must be achieved with neutral or cool white light. 2700K extra warm white 3000K warm white 3500K neutral white 4000K cool white 5000-5500K daylight 6000K cool daylight |
| Colour rendering index Ra | 80 |
?
Light sources can be classified on the basis of their colour rendering properties. The unit for colour rendering is called CRI (Colour Rendering Index, or CRI Ra value). The scale of the Ra is from 50 to 100. Ra = 90-100 excellent colour rendering properties Ra = 80-90 good colour rendering properties Ra = 60-80 moderate colour rendering properties Ra <60 poor colour rendering properties Fluorescent and PL lamps with an equal power, the luminous flux of Ra 90-100 tubes is typically 20% lower. |
| Colour temperature | 2800K |
?
Colour temperature is expressed in kelvin (K). The higher the colour temperature, the cooler the impression of the light: 2700K: extra warm white
Extra warm white creates a warm, inviting atmosphere (e.g. hotel, living room, and catering). Warm white can be used for a pleasant atmosphere (e.g. retail and office). Neutral cool white creates a more businesslike atmosphere, this color gives a sterile atmosphere.

| Diameter | 111mm | ? Diameter in millimetres, measured at the widest point. |
| Dim to warm | No |
?
Dim to warm is a dimming technique that adjusts colour temperature as the light is dimmed: it shifts from warm white to extra warm white when fully dimmed. This technique has various names, such as Dimtone or Glowdim. |
| Dimmable | No | ? Some lamps and ballasts are dimmable. There are different types of dimmers and different ways to dim a ballast or transformer. In case of insufficient knowledge, please check with our sales department. |
| Lamp base | G53 | ? Cap, lamp holder or lamp base type. |
| Luminous flux | 506lm | ? The amount of light transmitted by the light source per second. The unit of luminous flux is the lumen (lm). |
| Pieces per outer carton | 1 | ? Number of pieces per outer carton. To order full boxes of the item, please add it to your shopping basket in multiples of this amount. |
| Voltage | 12V AC (alternating current) | ? This may be either a fixed voltage or two values, in which case the product can be used within these limits. |
| Wattage | 11W | ? The power that the bulb consumes. This does not include the loss of any ballast or transformer. |
| Wattage equivalent | 50W | ? Replacement bulb power specified by the manufacturer. A CFL and LED display average 5x as much light compared to a standard bulb. To the CFL or LED power available divide the bulb power by 5. |
