should I change lamps or not? Help me decide on this please. I have Brilliance 6.5 lamps in a base bed. It metered 18.5 after 30 hrs. It now meters 17.8 and has 737 hrs on them. Shall I go ahead and change due to the sheer numbers are wait longer 70% mark which would be a meter of 12.9. The meter is working because I have metered other beds with different results. |
