Hi all,

I've purchased an older Halcyon 10W HID Helios can light with the unsealed/test tube head. Does anyone know a source, or at least the dimensions, of the test tube? If no tube is readily available, that info would help locate something from a scientific glass company.

As a bonus question, let's suppose my gorilla hands break the current bulb and the only spare I have. Would the replacement be a Welch Allyn/Solarc M10N001 or M10N003?

Thanks in advance!

Edit:
A little more digging reveals that EE still has bulbs on their website. That's good, because it's a specially modified bulb.

Edit 2:
The test tube is the same size as the 18 & 21w units, per Halcyon.

Looks like this is now an FYI post instead of an info request. Hope it helps someone, otherwise sorry for wasting bandwidth.
