replacement bulbs for Jandy spa light??

[newmaac]

I have Jandy color quartz halogen lights in my pool and spa.
I recently bought replacenemt silicone gaskets and bulbs for both units.
The gaskets are correct, and the bulbs are correct for the pool light, but much too large for the spa light.

I can not find anywhere online that gives the spae for these 8 bulbs.
I guess I can just take it apart and run to the store to replace whatever I find in there, but I would rather have the parts in hand before I pull out the light.

Anybody??

Thanks in advance,
Mike
