Dim center in lamps Has anyone seen lamps with dim centers or all around dim color? If so who was the manufacturer? What did they do about it? |
Re: Dim center in lamps Some manufactures use a little less neon gas. Sometimes the lamps will be less bright in the center but this has no effect on the output. Mostly seen in 2M lamps in vertical applications. |
Re: Dim center in lamps We sell all brands & see it with almost all 2 meter lamps in certain applications. Usually it corrects itself with proper lamp burn in & proper operating temp. One would think the brighter the lamp the better the output, that is not always true. The brightness is visible light, which plays no part in UV output. Here is part of technical bulletin from a lamp manufacturer on VHO lamps: Quote:

Re: Dim center in lamps John Ok VERY dim in the center and dont burn off or at least not right away. If a client walks out and says you have lamps out or sometimes they cant even tell the lamps are on would be a big problem right? |
Re: Dim center in lamps Yeah, that could be a problem. Have you tried them in any other units like maybe a laydown to see if it still happens? |

Re: Dim center in lamps John I am not using the Heartland stand ups any longer so we can rule out defective booths |
Re: Dim center in lamps It is important to make sure that you have the proper voltage coming from your power pole to the equipment. Beds will have different requirements based upon their ballasts and bulb configuration. I would check your voltage to the bed before blaming the bed or the bulbs. Use buck boosters to step up the voltage or down according to the manufacturers recommended voltage requirements. |
