I have a very large Halloween & Christmas display
But I'm not sure how only having blue bulbs could be "scarring"
My Halloween is not a blood & guts display....very non-scary
The scariest part is near the front door, black lights...skeletons that talk...a 6' one that has a microphone & I can talk
One little kid was scared so I turned the reg lights on & he was OK
My son loves decorating & each nite looks out to make sure things are turned on & the wind hasn't knocked anything over
I can see how going to stores looking for blue bulbs during the Christmas season could be scarring
I stay away from stores as much as possible during the Holiday season
I usually buy everything after Christmas or in a bulk order well before Christmas
Last LED order was for ~20,000 lights (strings of 50-100)
