Hi people
I use self ballast 250W MV lamps. It is a very common occurrence that when I try to switch on a lamp which worked perfectly fine the previous night, the lamp wouldn't switch on. And I would have to replace the bulb. What could be the issue please? I use a 15 metre extension cable to the lamp holder. Could this be damaging the lamps? There are no physical damages to the lamps nor burn out signs. Has anyone ever experienced this before?
Thanks
Regards
Jon

MV bulbs have to cool down before they can be turned on again. It’s normal for self-ballasted and nonself-ballasted bulbs.

I switch them on 24hours later...so ample time to cool down.

High Intensity Discharge (HID) bulbs will soon be a thing of the past. Most utilities are replacing HID bulbs with Corn Row Bulbs. Not only are the bulbs effective, they will last for many years, or even decades. They also use less energy and are more cost effective.
Should you ever find a retailer or lighting store with Clear Mercury Vapor Bulbs, purchase them all.

Are there any LED's which are suitable for mothing? Thanks |

I am not certain, but I think leptraps was indicating that the new bulbs are useless for attracting moths, hence his recommendation to buy all the stock in a shop if you find one that still has MV bulbs. I think that there are a few special LED light traps, but they may or may not be good at attracting moths. There was a thread about them on one of the forums (Insectnet or ICF) some time ago which indicated that they were not as good as older style moth traps. Adam. |

In my experience, LED bulbs hardly attract anything in comparison to MV bulbs. I used to collect at gas stations a lot until they switched to LED. Now it's just a waste of gas. Don't waste your money on LED bulbs.

There are only two types of bulbs that produce UV (Ultraviolet Light). Mercury Vapor Clear which requires Mercury (RU1) which is an HID (High Instensity Discharge) light Bulb.
The other is a Florescent Bulb. Each end of the Florescent Bulb has an ignitor which arches and activates the Florescent Coating on the inside of the tube and creates UV Light.

Are you sure the bulb is damaged? What happens without cable? The longer cable (15m is really long for this purpose) can have all kinds of effects.

I forgot to add that HID bulbs are designed for static use, not mobile.
