pdsgator,
You're talking apples and oranges. Globrites are a small light used for spas and water features. Intellibrites are a larger light used in larger bodies of water(pool rather than spa).
If you have globrites in the pool then you are not able to replace them.
Some finishes are darker and harder to light than a white plaster finish. Lights usually only provide a glow to the water and should not be bright. A lot of pools will have some shaded areas. This is the nature of light as it spreads through the water. I wouldn't think that shaded areas would be a safety hazard, but I understand your concern about the appropriate use of specific products.
Good luck.

I have read a number of posts where people are saying their pool builder is recommending glo-brite or shelf lights in the main pool area. I think they are just trying to cut costs by doing that. Globrites are designed for a specific use. They do not have the intensity or beam spread to light a large pool area. Unfortunately, they use very different installation methods. Globrites use a 2" PVC sleeve and teh niche goes in afterward. They don'e need any bonding. Regular Intellibrites use a niche that needs to be installed before gunite is shot, require bonding, etc. I have 3 intellibrites in my main pool area and one globrite on my shelf. I wish I would have put a globrite on my swim out also... it is dark. But the three intellibrites light my main pool area nicely.
