As a side note, those bulbs are available in H4 format in 60/80W with both low and high beams HIR in the same bulb, for those who have combination setups such as the JDMs and older landcruisers, but the price is quite steep at between $50 and $60 a bulb in sets of 2... |
The HIR's have the same life as a stock bulb, the GE versions were rated at a 1000 hour life expectancy (same as a standard 9006).
The bulbs you posted a link to are not a HIR bulb, they do not have the coating on them. If you have a truck that takes the H4 bulbs, there are now slight overwatt bulbs from Hella (Osram) that use a more efficient design and do not require wiring and harness upgrades. The bulbs are Hella Hyper bulbs:
65/70 watt 1350/2000 lumens
80/85 watt 1750/2400 lumens
55/60 watt- Standard 1000/1650 lumens
55/60 watt- high efficiency 1148/1895 lumens
For comparison the old overwatt H4 outputs are:
90/100 watt 1620/2400 lumens
100/130 watt 1820/3250 lumens
These big overwatt lamps should not be run in the 80, they will melt the housings.
The 65/70 and 80/85 bulbs are available from rallylights.com and daniel stern lighting. They run about $20 each.
