Gosh, I use four antique Kodak safelights with 15 W bulbs in my darkroom and they are fine. I test things maybe once a year, and find no problems. If I were to buy new, I probably would go for the LED's too, but the old ones were bought for practically nothing, and 15 W bulbs last nearly forever too.
In any case, I agree with David Brown. Why risk fogging and other problems after you've spent all that money and time to get good negatives. Don't make sense.
