Dear members:
This may not be the ideal venue for this question but I know of no other so
I decided to ask for your expert advice on this as well as a few other
questions I will post. This is my first post to the group as I have been
lurking for a while learning from your exchanges. Please forgive me if my
questions are somewhat basic in nature.
I am currently searching for a desk lamp. My needs are quite specific - I
need a desk lamp with bulbs that can provide a correlated color temperature
of 5400-5500 K, a CRI greater than 90 (preferably greater than 92) and the
same spectral power distribution (SPD) of daylight. So far I have contacted
Osram, Sylvania and Philips but they only offer 8' bulbs with these
characteristics. I initially thought about purchasing a standard desk lamp
and replacing the bulb but it seems no bulbs (at least not from the above
companies) with the characteristics I described above are available for
small desk lamps.
The only lamp I have been able to find is the STE-155 from Waldmann
Lighting. According to them this lamp comes with a single 55 W light bulb
made in Germany that provides a CCT of 5400 K, a CRI of 92 and SPD of
daylight. The bulb uses a 2G10 base/connector. The only problem is the price
- the lamp retails for approximately US$ 600 which is a really high price to
pay for a desk lamp.
Do any of you know of alternatives that would be provide me with the
lighting characteristics listed above and for a reasonable price ? Would you
know any company that manufacturers bulbs with the above characteristics ? I
am also looking for bulbs that can be mounted on standard screw-type sockets
used for conventional incandescent bulbs with the characteristics above. Any
ideas or suggestions ?
Thank you in advance for your help and suggestions.
Best regards,
Joseph Chamberlain |

you may want to check http://www.solux.net
I don't have personal experience with that product,
but it might be what you are looking for.
