Whats the difference between OSRAM POWERSTAR HQI-T 250W DAYLIGHT and OSRAM POWERSTAR HQI-TS 250W DAYLIGHT?

what does the T and TS mean. Also where can I find out the dimensions of these bulbs. I've checked out the osram sight already.

T means Daylight (from the German - Tageslicht)
S means Shielded (UV barrier)

thanks for that reply. What is daylight then?

Daylight refers to the temperature. Usually a 500k to 6500k lamp is daylight.

Goto the osram or ge-lighting websites for detailed explanations of these things.

The upper-tier HQI-TS lamps don't have an external envelope....

Or do you mean UV-coated.

Take a look at this: http://www.osram.no/brosjyrer/english/K01KAP5_en.pdf

The -T version is larger and got an E40 socket, -TS is two-sockled.
Both seems to have UV-filter.
Not sure wether daylight means /D, /NDL or /WDL though, that defines the color temperature.

Pardon the typo,

Daylight is 5000k (not 500 k lol) to 6500k

The shielding is from the quartz not an additional outer envelope.

D was used for durable hence the T for daylight.

Id select text but the pdf wont allow it - see attached.
This is from an OSRAM document, other manufacturers may use other terms!

D= 5000k - 5800k Daylight
NDL = 4000k - 4800k Newtral or near daylight
WDL = 3000k - 3800k Warm daylight
