INCANDESCENT, full spectrum is the most desirable type of light. It can be achieved with energy efficient T series FLORSCENT bulbs with a high color rendering index (CRI) 90-100.For bulb selection1. you need to know the dimensions of the room;2. how BRIGHT you want room lighted as measured in LUX;3. the COLOR of light in KELVIN;4. and the QUALITY of the light measured by the color rendering (CRI) index.5. select the appropriate bulb and note how many LUMENS of light it will produce.Then calculate the number of florescent bulbs with the your CRI rating as necessary to accomplish the task and with power consumption in mind (WATTS), select the type of fixture.LUX (Lx) BRIGHTNESS IN LUXOne Lux - is one lumen per square meter.3.4 lux - twilight50 lux - living room80 lux - office hallway100 lux - overcast day350-500 lux - office lighting400 lux - sunrise1000 lux - overcast day10,000-25,000 - daylight32,000-130,000 - sunlightKELVIN (K) is the COLOR of the LIGHTcalled COLOR TEMPERATURE3000K warm white4200K cool white5000K - daylight2700 K - residential lighting (Incandescent light)3000-3500 K - neutral-white4100 K - cool-white in offices5000-6500 K - blueish-whiteCRI is the QUALITY of the lightcalled the COLOR RENDERING INDEXand is a measure of how well colors can be perceived.100 CRI - incandescent lamp50-100 CRI - fluorescent tubes82-100 CRI - natural color (full spectrum)POWER CONSUMPTIONas measured in Watts. Incandescent lights are full spectrum but are energy hogs. Florescent lighting is more energy efficient.The high efficiency bulbs are labeled with T - T12, T8, T5 etc..."T" is the diameter of the tube in the lamp. Typically narrower the lamp diameter the more efficient it will be.T12s have not bee manufactured since 2012.Content rating: Everyone
