whoops! my mistakeJono wrote:I was looking on the Narva website and it says the Narva HB3 +30's are 60w not 65w...

After reading Jono's message I went fishing through the rubbish bin to find the packaging from the globes. They are 60W!

So Jono, you've got the rights ones!

Clarification
Standard FTO globes: 51W HB4 (around 1,000 lumens)
The upgraded globes I used: Narva 60W HB3 +30 (around 2,000 lumens)
The Narva +30's were produced a whiter light than what the standard globes did.
If you want to increase the brightness further or if you want to use a tinted globe to get more of a HID colour, then it would pay to use a slightly higher wattage globe. You should have no issues with 60W, 65W or a 70W bulbs, above this and you might introduce heat and power issues.
