My Wipac spots have not worked for a while now and I’m going to bin them and replace with LED. They are mounted in front of the grill on the bumper. Can anyone recommend something inexpensive but adequate? Or would a light bar be better.?
What are you actually wanting?
I know everyone always calls them spot lights, but spots are for long distance. A light-bar typically is a flood lighting device. So a different result for a different purpose.
Are you wanting to have more light directly in front and to the sides (flood) or are you wanting to put light a lot further down the road (spot)? If you want both, you may been more than one thing, or you'd need to look at some combo items.
As a general trend, spot lights need to have physically larger reflectors or optics. As this will focus the light more. Smaller reflectors or optics are normally tailored for flood light.
Many LED units use clusters of small LED units and optics, so as a rule (not always) will tend to be more floody than spot.
Lightbars can be had from various prices. Ebay sell Chinese ones from about £50, but if you go through a specialist 4x4 shop, you could easily spend £500 on something that looks very similar.
The pitfall with LED units is the quality. Cheap ones may not always be constructed as well, or won't be as waterproof. And while the physical LED will last a long time. The electronics that run them can be more fragile. Then there is the quality and type of LED. Very white light (or sometimes blueish) is harsh on the eyes, causes eye fatigue and bleaches colours out. In urban areas they are ok, but in rural or countryside you'll find they make everything look a lot more grey with a lot less definition. LED units with a warmer or neutral colour temp are harder to find, but work so much better when you have trees/grass, etc that you are lighting up.
The actual output of a lightbar can vary a lot too. Most of the claimed outputs are nearly always lies. Especially for the cheap ones. So this can greatly impact how good or bad they are. Best bet is to go off of reviews for a specific item.
On the flip side, the expensive lightbars from the trendy 4x4 stores. These will generally work well, but are often grossly overpriced. A lightbar they are selling for £500, might be available unbranded for £120.
