Dive Rite 21 HID vs Halcyon 18 HID

[DeWayne]

The WA 18w and 21w bulbs are the same, just the ballast is different for the different outputs. DR original 18w was a WA assembly. They have now gone to a 21w bulb and ballast from a different manufacturer which has a different design than the WA...not interrchangable. I had a DR 18w light head, but the ballast went out and I did an exchage for an H1 10w. But I also have a custom made 21w from head from Germany. This head uses a WA assembly and will accept the DR "18w" WA bulbs. I am not sure what Halcion is using for their 18w and 21w heads.

Thanks for answering my question before I asked it Lee. I understood previously that the WA bulbs were in fact the same with different ballasts, so I was curious if DR had changed suppliers. Do you know who is making the new bulbs and ballasts for them?

My understanding is that the new DR head components come from the far east (e.g. China) - I do not know the name of the company.

Thanks Lee, I was not aware of the change in manufacturer.
