Thank you for your question. This lamp generates 2800 lumens and has a color temperature of 6500K.
I PUT 8 AROUND THE TOP OF MY WIFES BATH MIRROW SHE HAS MACGULAR DEGENERATION HAS BEEL LIKE GETTING HER SIGHT BACK ALMOST I HAVE A 8X10 SMALL WORK AREA I NEED A LOT OF INTENCE LIGHTING AN I HAVE 20-20 SO I PUT 6 IN THE SMALL AREA MAN IT NICE TO BE ABLE TO SEE WITH LESS EFFORT. AN I HAVE THEM IN ALL 3 BATHROOMS SMALL ON JUST 3 KNOW U WILL LIKE IT
This bulb consumes as much electricity as a standard 40 watt incandescent bulb. It will be fine for your floor lamp.
Never put a meter on it, but understanding how a fluorescent light actually works might help. A fluorescent bulb uses an electrical discharge to excite usually mercury vapor in an argon gas environment to produce UV light. Since we can't see UV, they coat the inside of the bulb with a coating that reacts to the UV causing it to glow, white in this case. It actually floureses like your black light paints. The coating stops the bulk of the UV from escaping. Is it enough to get a tan, nope. Permissible exposure levels are usually rated at 10cm distance for 8 ish hours. This larger lamp, probably a little less time, hence more UV. To put things into perspective, the permissible UV exposure in Death Valley in broad daylight in the summer is rated at 6 to 7 minutes, then you're toast. If you are trying to prevent any UV exposure because say, you're in a museum and have to prevent degradation of ancient artifacts, then I would not recommend any fluorescent lamp. Hope this helps.
6500K is the best for growing foliage on plants. 2700K is best for flowering.
The life of this CFL is specified at 8000 hours. The price is higher because it puts out the equivalent of a standard 150W bulb but consumes only 40W of electricity and lasts much longer.
2800 Lumens Very bright.
The amount of heat a light bulb produces is directly proportional to the wattage of the bulb. In this instance, a 40 watt CFL will produce roughly 2/3 the amount of heat of a 60 watt incandescent bulb.
It should. I use it as an indoor plant light. Better simulates natural sun.
