Osram 150w HQI-TS NDL: Evolution of the Powerstar

Osram 150w HQI-TS NDL: Evolution of the Powerstar

Click to view full size image

Two Osram HQI-TS lamps in 150w NDL flavour.
One old style and one newer generation lamp.
It's interesting to note on the new lamp how the arc tube is fused to the outer envelope, is of a new more rounded design and now sports a starting aid.
It's a completely different design to the old "halogen lamp with an arc tube" traditional double-ended discharge lamps.

The new lamp can retrofit the old lamp. The starting aid, is a wire around the arctube, which I don't see here, and is added because of the removal of the Kr85 from the gas filling. We have the new lamp in a cheap chinese floodlight at our hostel, and it takes about 3 mins to run-up and 8-9 mins to restrike (The floodlight have a local made Eltam magnetic ballast, and either Eltam/Chinese superimposed ignitor).
