Where to buy UV Glass for MH???

[reeflobang]

Just installed my BLV DE 150W 10K MH and though advised that its UV safe.... but my light-sensitive glasses turn super dark under this light....... this only happens when I am outside on a clear sky and noon time..... tried to shine a strong bulb and also a bright LED white light onto my glasses but nothing happens.. just under the MH it happens...... very worried about the damage to one's eyes....

Bought my set from Victron.... those who did... are u assured its safe?

Have you try using your glasses test technique on SE bulb?? I guess both will have this problem, with DE being the champion ..

So is DE bulb really UV shielded? or for that matter is SE too? and do DE casings usu come with UV shielding glass?

Just read in one of the scientific website that mentioned that normal glass actually absorbs UV but did not mentioned if its UVA, UVB or UVC.... more confused.... one of sun-caused UV is effectively blocked by ozone layer but how about those created by MH lights....????

[ervine]

Yes glass effectively blocks UV radiation... but I also cannot remember which one does it block... learnt it last year.. darn...

I thought it blocks both... HMmmm.... there's one that is a lot more damaging...

I think UVA is the more damaging one. anyhow can anyone offer his 2 cents on this issue? what is the actual UV shielding for SE,DE and their casing glass?? hhhmmm maybe will start new thread.
