Hi
I have 3 public moth trapping sessions coming up and big brother H&S now dictates I should protect my MV bulbs to prevent injury from bulb explosions. I need to construct some bulb guards. I don't want to use a pyrex bowl because of heat build-up causing bulb coating degeneration thus reducing efficiency over time and the difficulty of attaching to an bulb attached to a tripod over sheet. Looking at thermal properties I reckon some stainless steel mesh would be suitable but wonder about the mesh & wire size. I would have to trade off-protection vs light emission and wonder if anyone has any experience with different mesh & wire sizes to give the best trade-off. I am looking at something like: http://www.ebay.co.uk/itm/Stainless-Ste ... 1e7015c9fc
Any help/suggestions appreciated.
Thanks

Jeez, do-gooders strike again! Sorry Liz, have no experience of bulb guards. I know ALS sell one.

Yeah, and everyone's meant to wear UV protection glasses.
I saw those but buy one???? :shock: when I can make one? Maybe I'll start a little side-line in bulb guards since big brother is ever-growing ;)
