Does anyone know the difference in these two and if it is OK to use the 912's in my fixtures?
Question 2.....We have two of the little ceiling fixtures on the underside of the cabinet over the bed just above where we sleep. I suppose these are mostly for reading and the like. Are there lower wattage bulbs that would not be so bright?
The 921 and 912 are interchangable, both T-5 bulbs with a wedge base. The difference between the two bulbs is the wattage and amperage use. The 921 has a wattage of 16.8 and draws 1.4 amps. The 912 is 12 watts and draws 1 amp. So the 921 should burn brighter than a standard 912 bulb. The only thing I could find on the 912NH is that is was listed as 13W but didn't give an amp draw and was listed as having 20% 'brighter light'.
All my lighting fixtures have a small label attached near the bulb socket, it will usually list the bulb size or do not exceed. Not knowing the bulb size, I would not be able to suggest a replacement bulb that will reduce the wattage and thus lower light output. If you can give the bulb number from the label or bulb...I will try and give you something that might work.
If it's like mine it has a 1141 bulb that burns at 18.4 watts. Might try a 1003, which should fit the base and runs at 11.4w.
