Can I have fewer lights in the pathway lighting system and use larger bulbs?

Of course you can. You have 88w to play with. Use any combination of smaller/larger bulbs to get the look you want.

Hello and Thank you for your question. The answer is yes you can. It is common to experiment with different wattage wedge base bulbs. However just be aware that the fixtures were designed to be used with 4watt bulbs. The heat from an 11watt bulb is greater than the 4watt and has the potential to cause damage to the fixtures over time. There is also a 7watt wedge base bulb that may provide sufficient light performance.
