esantoro Posted May 16, 2009 Report Posted May 16, 2009 (edited) Among my list of obsessions, lighting is one of them. I was doing a bit of spring cleaning and came across a 23 watt/6500K full spectrum compact fluorescent daylight bulb that fits a regular incandescent socket. I would say this bulb out performs a 100 watt incandescent for amount and quality of light. Here are the specs: Company: Sunlite Manufacturing (in Brooklyn, NY, though the bulb is made in China) Model # SL23/65K Cat. No. 05454 I've bought daylight/sunlight bulbs in the past. This is the only one that has impressed me. ed Edited May 16, 2009 by esantoro Quote
esantoro Posted May 16, 2009 Author Report Posted May 16, 2009 This would be nice to go with the bulb: http://cgi.ebay.com/Magnetic-Tool-Lamp-Lig...bayphotohosting Quote
esantoro Posted May 19, 2009 Author Report Posted May 19, 2009 This would be nice to go with the bulb:http://cgi.ebay.com/Magnetic-Tool-Lamp-Lig...bayphotohosting These lamps are available from Harbor freight for $10. I've ordered three to outfit with the full spectrum compact fluorescent bulbs. My earlier comparison is between 22-watt circline daylight bulbs and this spiral compact fluorescent. I've noticed that spiral cf puts out a whiter light than the daylight circline, which puts out a more yellowish light, though it is also supposed to be 6500k. one hour of use of this 23 watt spiral cf bulb consumes .02 kwh. A regular 100 watt incandescent consumes .07 kwh in one hour. The spiral cf bulb consumes 71 percent less electricity than does the 100 incandescent. I'd like to put one of these spiral cf bulbs in my Danray lamp but I need to find a bulb that does not stick out as much, as the lamp's safety grill will not fit. ed Quote
Bree Posted May 19, 2009 Report Posted May 19, 2009 I am using one of these on my Toro 4000 LA-25 http://www.verilux.com/clamp-lamps/shoplight-shop-lamp The full spectrum lamp on there is just terrific and I love it. They are cheap but they sure put out high quality light in quantity. Quote
esantoro Posted May 19, 2009 Author Report Posted May 19, 2009 The Verilux lamp is on my list, but the Harbor Freight magnetic lamp and spiral CF 6500k bulb I mention is a $17 alternative that I stumbled upon. ed I am using one of these on my Toro 4000 LA-25http://www.verilux.com/clamp-lamps/shoplight-shop-lamp The full spectrum lamp on there is just terrific and I love it.

esantoro Posted May 19, 2009 Author Report Posted May 19, 2009 I'm thinking of getting a 40 watt/200 watt equivalent daylight fluorescent spiral bulb to go into the magnetic lamps that are arriving. One will go over my computer area. One will go over my stitching area. And one will go over my skiving/drill press area. I like the results from the bulb I've already mentioned, but then I found this 40-watt bulb. http://www.amazon.com/exec/obidos/ASIN/B00...K/thedourol-20/ I need to do some checking to make sure that this bulb is 6500k and not 6000k. Is there any reason I should think twice about going beyond 100 or 150 watt equivalency with these daylight bulbs? ed Quote
esantoro Posted May 20, 2009 Author Report Posted May 20, 2009 I did a bit more legwork on daylight bulbs. The Sunlite bulb that started this thread is of the following rating: lumens: 1300 Energy used:23 watts Incandescent equivalent: 100 watts Avg. hours: 10000 Avg. cost: $7 CRI: 82 Color temperature: 6500k I've already stated that I like the results of this bulb.............................................Buuuuuuuuuuuuuut, can I go better. I found a more affordable bulb online that has slightly better specs: Company: Megalight Energy used: 23 watts Incandescent equivalent: 100 watts Avg. hours: 12000 Avg. cost: $5 (includes shipping) if you buy at least six at a time CRI: 85 Color temperature: 6500k Going by just the specs, this Megalight bulb should be even more of a full spectrum bulb, but I wonder how much these specs can be trusted and whether some bulbs may perform better at mimicking natural lighting than other bulbs for unexplainable reasons. ed Ordering Code 23W/6500K Spiral Product Number S28023-6500 Energy Used 23 Watts Volts 120 Bulb Shape Spiral Base Medium (E26) Diameter (in) 2.4 Length (in) 5.000 Average Rated Life (hr) 12,000 Light Output 1,450 Lumens Finish Daylight White CRI 85 Color Temperature (Kelvin) 6500K Common Cross-References GE: No Available Direct Offset Osram Sylvania: No Available Direct Offset Additional Information ProductNotes: Quote
MADMAX22 Posted May 20, 2009 Report Posted May 20, 2009 You do some interesting research Esantoro. I also wonder how accurate the specs are. Companies love to massage specs to make there products look better or to fall in spec with minimum requirments. Quote
